Hidden charges like resort fees that could double the price of your hotel room
The fees are charged even if you don't use the amenities in the hotel
ALWAYS read the fine print if you're booking a hotel as otherwise the super cheap room you're booking could end up costing you more than double of what you're expecting to pay.
This is because some hotels are now charging hidden fees, which are only mentioned in the terms and conditions - if at all.
Resort fee
One common charge that isn't always explicitly mentioned is the "resort fee" - which charges you for on-site amenities even if you didn't use them.
While you're most likely to encounter it in the US, you could find it anywhere.
Resort fees can include anything from the gym and swimming pool to internet and phone calls.
The average resort fee is an additional $30 (£23) a night, , although some hotels charge as much as $160 (£125) a night - which can end up doubling the cost of your hotel stay if you manage to find a cheap deal.
If you're booking via a third party, this is not always made clear.
.You can get out of paying resort fees if some of the amenities are not up to scratch - for example, closed pools or slow WiFi.
Or if you're a member of the hotel's loyalty program, sometimes these fees are scrapped.
A Booking.com spokesperson told Sun Online Travel: "As an extension of our overarching aim to provide our customers with transparent information about the total price they will need to pay at a property when they make a booking and to create a level playing field for all of our accommodation partners, we are updating our process when it comes to charging commission on mandatory extra fees that customers are asked to pay at the property."
Resort fees currently only affect Brits heading to countries such as the US as they do not exist in the UK due to pricing laws.
Other hidden fees
While resort fees are the most common hidden fee, there are plenty of others levied by unscrupulous hotels.
You might have to pay taxes or other local charges at your hotel, such as a tourist tax.
Some hotels are charging guests an "Urban Destination Charge" if they are near popular landmarks.
Hotel chains in New York have been accused of adding an extra $25 (£19) a night if they are near Times Square.
Booking websites have also been accused of hiding additional fees such as resort charges.
