10 Hidden Costs Of Travelling You Need To Know About
The most common hidden travel costs include ATM and foreign transaction fees, tourist taxes, international roaming charges, mini-bar overspending, extra baggage fees, tipping, hotel WiFi charges, departure taxes, and temporary driving licences. Planning ahead - using a fee-free card, a global eSIM, and a luggage scale - can save travellers hundreds of pounds per trip.
Key Takeaways
- Currency exchange and ATM withdrawals abroad can add £2.50–£10 in fees per transaction, plus up to 3% in foreign transaction charges.
- Tourist taxes are common across Europe and the USA and are rarely included in the advertised room rate.
- A global eSIM avoids international roaming charges without needing a local SIM card.
- Mini-bars, room service, and hotel WiFi are among the easiest hidden costs to avoid with basic planning.
- Departure fees, temporary driving licences, and tipping customs vary by country - check before you fly.
1. Currency Exchange Fees
Exchanging currency and withdrawing cash abroad can cost you £2.50–£10 in fees per withdrawal, plus up to 3% in foreign transaction charges on some cards. Do your research before you travel to get the best exchange rate - many currency exchange providers will also buy back your leftover foreign currency for free when you return home. Check whether your bank is part of a network with international partner ATMs to avoid withdrawal fees, and confirm whether your card charges a foreign transaction fee before you travel.
2. Additional Tourist Tax
Tourist tax is common across Europe and the USA. In Venice, for example, hotels charge a tourist tax to all visitors, usually a few pounds or dollars a day. Destinations like the USA add sales tax to almost every purchase, so the price on the shelf is rarely the price you pay at the till. When you arrive, ask a local or someone at your hotel what extra charges to expect before you buy.
3. International Roaming Charges
Pay-as-you-go roaming rates can run to £50 or more per day once you start using maps, messaging, or calls abroad - even if you don't plan on using your phone much. A global eSIM, like WorldSIM's International eSIM, covers 195+ countries through 500+ local operators, includes free incoming calls in over 100 countries, and comes with a UK number included at no extra cost. That means if you land with no taxis in sight or get lost with no one around who speaks your language, you can call a cab or pull up a map immediately - without a shock bill waiting at the end of your trip.
4. Room Service and Mini Bars
Room service and mini-bars are an expensive way to get food and drink in your hotel room - some hotels even have sensors in the fridge, so moving an item can trigger a charge. Keep a few snacks and a bottle of water bought from a local shop in your room so you're not hit with a large mini-bar bill at checkout.
5. Getting To and From the Airport
Driving to the airport and paying for two weeks of parking isn't always the cheapest option - a taxi, coach, or train can work out cheaper depending on your route and flight times. Plan how you'll get from the airport to your hotel on arrival, and remember you'll need a way back to the airport at the end of your trip too. Check with your hotel for the best option before you travel.
6. Extra Baggage Fees
Overpacking or bringing home too many souvenirs can mean a small fortune in extra baggage fees. A luggage scale is inexpensive and lets you check your bag is within the allowed limit before you leave for the airport, saving you from a costly surprise at check-in.
7. Tipping Customs Abroad
Tipping etiquette varies significantly by country, and it's easy to spend more than expected on service charges without realising it. Ask a local or someone at your hotel how much to tip and when it's expected, or check a guidebook before you travel so you know the local etiquette in advance.
8. Hotel WiFi Charges
Not all hotels include WiFi for free - some charge a daily fee. Check this before you travel so you can plan alternatives if needed. If WiFi isn't included, a pocket WiFi device can work out cheaper than paying a hotel's daily rate, and saves you hunting for a free WiFi café on holiday.
9. Departure Fees
Most departure fees are included in your plane ticket, but not all of them. Several countries, including Hong Kong, Cambodia, Costa Rica, and Colombia, charge a separate departure fee - even if it isn't your final destination. These can add up quickly across a multi-stop trip. Confirm with your airline whether any departure fees apply to your route before you fly.
10. Temporary Driving Licences
Many countries, including St Lucia, require a temporary driving licence if you want to drive during your trip. These usually come at a small cost, so it's worth budgeting for. Check with the airline or the embassy of the country you're travelling to for the exact requirements and cost involved.
