Why holidays on small islands without ATMs, cards, and reliable signal often become more expensive than expected

Why traveling to islands without ATMs and cards can become more expensive than what is written in the booking

Booking accommodation on a small island often looks simple: an overnight stay has its price, the ferry has a published sailing schedule, and the total cost of a holiday can, at first glance, be calculated in a few minutes. But the actual bill often begins to change only after arriving at the port, entering the ferry schedule, and making the first attempt to pay at the destination. On islands with few shops, a limited number of catering establishments, weaker signal, or no ATMs, the difference between the planned and actual cost can arise very quickly. It does not have to be a hidden scam or an unfair practice, but a sum of circumstances that are almost invisible in large cities: cash is more necessary, an ATM is not always nearby, a card terminal depends on the connection, and returning to the mainland because of a missed boat can mean an additional day, a new overnight stay, or more expensive private transport.

In the euro area, cash is still an important part of everyday payment, and the European Central Bank emphasizes that access to cash and its acceptance remain essential for the function of euro banknotes and euro coins as legal tender. At the same time, card payment in tourist countries has become common, so travelers often start from the assumption that a card will be enough for every expense. That assumption can be correct in larger coastal centers, ferry ports, and developed destinations, but on smaller islands it does not always work in the same way. Card payment is possible where the merchant has a terminal, a stable connection, and a business model that accepts electronic transactions; where this is not the case, a booking paid in advance covers only part of the trip, and not everything that happens between arrival and departure.

The most expensive cost is often not accommodation, but the wrong assumption

When traveling to islands, the problem rarely begins with a large item that has been completely left out of the plan. More often, it arises through a series of smaller expenses that appear at the wrong moment. For example, a traveler may pay for an apartment in advance and buy a ferry ticket, but only on the island realize that the nearest shop accepts only cash for smaller amounts, that taxis or local transport do not accept cards, that delivery from a more distant place is more expensive than on the mainland, or that because of a change in the weather it is necessary to adjust the return. If there is not enough cash, then the cost is not measured only by the cash withdrawal fee, but also by time, transport to the ATM, possible waiting for a new line, and the unpleasant limiting of everyday decisions.

Croatia is a good example of such dynamics because traffic to the islands is strongly based on public ship, fast-ship, and ferry lines. The Agency for Coastal Line Maritime Transport for 2026 lists a large number of state lines with a public service obligation, from ferry connections to Cres, Pag, Brač, Hvar, Korčula, Pelješac, and Mljet to ship and fast-ship lines that connect smaller islands such as Olib, Silba, Premuda, Rava, Iž, Zlarin, Kaprije, Žirje, Unije, and Susak. Such a network enables accessibility, but it does not mean that every place has the same financial and digital infrastructure.

It is especially important to distinguish the price of travel from the price of the stay. A ferry or catamaran ticket covers arrival on the island, but it says nothing about how much transport from the port to the accommodation will cost, how far away the shop is, whether there are evening lines, whether the ATM works outside the season, whether a smaller catering establishment accepts cards, or whether there is an additional fee for luggage, a bicycle, a pet, or a vehicle. With car ferries, the additional cost can also be the vehicle, and when traveling without a vehicle, luggage transport and local mobility become more important than they seem at the moment of booking.

Cash is not an outdated habit, but a safety reserve

Although cards dominate many tourist transactions, cash on smaller islands retains a practical role. It is not only an alternative to a card, but insurance in situations when the terminal does not work, the signal is unstable, the merchant does not accept cards for small amounts, or the only available transport is more informal than in the city. The European Central Bank points out that the euro area strives to preserve broad availability and acceptance of cash, precisely because it is a means of payment that does not depend on digital infrastructure. On islands, a terminal failure, loss of connection, or limited ATM working hours can have greater consequences than in the city.

Cash, however, does not solve all problems if the traveler brings it in the wrong amount or denominations. Large banknotes can be impractical in small shops, at stalls, or with local service providers, especially early in the morning or outside the main season, when turnover is lower. On the other hand, too little cash can mean that every purchase turns into a calculation. A more realistic approach is a combination: a card for larger and pre-planned expenses, enough cash for several days of basic needs, and checking whether there are ATMs in the place of arrival or only in a larger island center. At the same time, one should also count on the possibility that the ATM is empty, out of order, or several kilometers away from the accommodation.

The question of fees is also important. The Croatian National Bank maintains an overview of bank fees for the most commonly used payment services, and from 2026 in Croatia a legislative framework applies that introduces a package of free banking services for certain consumers, with individual rights that apply in phases. But such regulations do not mean that every cash withdrawal at every ATM, especially for users of foreign cards or cards outside the home network, will be without cost. The traveler must therefore distinguish between their bank's fee, the ATM owner's fee, currency conversion if the account is not in euros, and a possible unfavorable offer of dynamic conversion on the device itself. On an island with one ATM, such a mistake is not just a financial trifle, because alternatives may be limited.

The ferry schedule can change the entire budget

The published price of accommodation often assumes that arrival and departure will go according to plan. On islands, that plan largely depends on the sailing schedule. Jadrolinija enables searching the sailing schedule and buying tickets online on its official pages, but at the same time warns that the sailing schedule is subject to change. In practice, this means that travel is not only a question of the ticket price, but also of coordinating arrival at the port, boarding, possible waiting, seasonal demand, and the return connection to the airport, station, or other transport. When the line is rare, a missed boat is not a minor inconvenience but an event that can change the entire budget.

With larger and more frequent lines, the consequences are usually smaller, because the next departure comes relatively quickly. With smaller islands and seasonal fast-ship connections, the situation can be more sensitive. If the traveler relies on the last departure of the day, any road delay, boarding crowd, flight delay, or ticket problem can produce a chain effect: an additional overnight stay on the mainland, a transfer change, later check-in at the accommodation, a surcharge for late arrival, or the loss of an already paid holiday day. In the other direction, leaving the island too early for safety can mean paying for more expensive accommodation in the port or an additional meal, even though the basic booking was favorable.

That is why, with islands, it is especially important to read the transport conditions, and not only the ticket price. Jadrolinija states in its frequently asked questions that a ticket can exceptionally be bought on board if the agency is closed, but it recommends purchase through the website or application. For the traveler, this means that digital purchase can reduce risk at the beginning of the trip, but it does not remove the need for cash and a backup plan on the island itself. With vehicles, it is necessary to check whether the ticket is valid as a reservation of a place on the selected line, how special cargo is treated, and how much earlier one should arrive at the port. For passengers without a vehicle, it is necessary to check where the port is located in relation to the accommodation and whether there is local transport after the arrival of the last line.

A weak signal turns a card into a piece of plastic

Card payment does not depend only on the bank and the card, but also on the connection between the terminal, the merchant, and the payment system. On many islands, mobile coverage is good, but coverage on a map is not the same as a stable connection on every beach, in every cove, or in an old stone house with thick walls. HAKOM publishes coverage maps of operators' mobile networks and clearly notes that the data are informative and that the actual user experience may differ depending on circumstances and network load. This warning has a very practical consequence: a terminal may work in the morning and stall in the evening; the signal may be good in the port and weak in a more distant hamlet; a banking application may open slowly exactly when a payment needs to be confirmed.

At the peak of the season, network load can also be a problem. A small place that has several hundred inhabitants in winter receives many times more people in summer, and everyone uses navigation, mobile banking, and communication applications. If the merchant has only one terminal or relies on mobile internet, every instability slows down payment. In larger cities, the customer then goes to another establishment; on a small island, another establishment may not exist or may be half an hour's walk away.

Digital dependence is also visible in travel organization. Electronic tickets, booking confirmations, instructions for entering the apartment, host contacts, vehicle rental, and mobile banking are often stored on the phone. If the battery runs out, the signal weakens, or the application does not load the confirmation, a simple situation can become more expensive. It is therefore reasonable to save tickets and confirmations offline before departure, record important information, bring a power bank, and have at least one paper or locally stored proof of booking. Such measures do not increase the cost of the trip, but they reduce the risk that due to a technical problem additional transport, a new ticket, or an unnecessary service is paid for.

Surcharges that are not hidden, but are often forgotten

Some additional costs on islands are completely legitimate and publicly listed, but they remain outside the mental calculation until they appear at the cash register. Transport of a vehicle, bicycle, larger cargo, or pet, transfer from the port to a distant cove, parking in the departure port, grocery delivery, use of taxis late at night or extraordinary transport by boat can change the total price of the holiday. On some lines, the price of a ticket for a person and the price of transporting a vehicle are not the same category of cost, and travelers who compare only the price of the overnight stay often forget that a car on the island can be an advantage, but also a significant item in the budget.

The same applies to accommodation. A lower apartment price in a more distant place can be a real saving if there is a shop, beach, and regular connection with the port. But if every purchase requires a taxi, scooter rental, additional fuel, or arranged transport, the price difference quickly disappears. Accommodation that is a few kilometers from the port on the map can be demanding if the road has no public transport, if arrival is late in the evening, or if traveling with children, older people, sports equipment, or larger luggage. Therefore, the total price is not only the sum of accommodation and the boat ticket, but also the price of moving around the island.

With smaller destinations, seasonality should also be taken into account. In the pre-season and post-season, accommodation prices may be more favorable, but the working hours of shops, catering establishments, tourist services, and transport may be shorter. In the main season, the choice is greater, but the pressure on lines, accommodation, and local services is stronger. In both cases, a lack of planning can increase costs: outside the season because there are not enough available services, and in the season because the remaining options are more expensive or sold out.

How to calculate the price of an island trip more realistically

The most reliable calculation starts with the question of what happens if the simplest option is lost. If the card does not go through, is there enough cash for a meal, transport, and basic groceries? If the ferry is missed, is there another departure the same day? If the ATM does not work, where is the next one and how does one get to it? If the signal weakens, are tickets and contacts available offline? If the accommodation is outside the place of arrival, how much does the transfer in both directions really cost? The answers to these questions often reveal that the cheapest booking is not always the most favorable, especially when time, risk, and limited infrastructure are included.

It is useful to make an island budget in three layers in advance. The first layer consists of fixed costs: accommodation, ship or ferry tickets, transport to the departure port, and planned transfers. The second layer consists of everyday costs: food, water, local transport, sun loungers, excursions, fuel, parking, and small purchases. The third layer is a reserve for disruptions: an additional overnight stay, private transfer, ticket change, medical need, vehicle breakdown, or weather change. Only when all three layers are added together does the price of the trip begin to resemble the actual cost, and not an advertisement from a booking system.

In that calculation, information from a local source has a special place. Official pages of carriers and regulators should be used for the sailing schedule and lines, banks and card companies for fees, and the host or local tourist board for practical details: the nearest ATM, shop working hours, the possibility of card payment, taxi availability, and the real distance from the port. Such a check does not have to reduce the appeal of a small island; on the contrary, it makes it possible to experience the peace, isolation, and slower rhythm without the financial pressure that arises when city habits are copied onto a place with different infrastructure.

An island trip is therefore not necessarily more expensive than what is written in the booking, but it becomes more expensive when the booking is misunderstood as a complete cost estimate. Smaller islands offer precisely what makes them attractive: distance from crowds, a simpler rhythm, and a smaller number of services. Those same features mean that money, transport, and connection must be planned more carefully. A card, application, and online ticket are useful tools, but cash, a checked sailing schedule, and a realistic reserve are often the difference between a holiday that stays within the budget and a holiday whose actual cost is discovered only when the choice has already narrowed.
