Most travellers would make use of in-room mini bars and fridges more often if prices weren't "such a rip-off", according to research from travel booking website TripAdvisor.
A poll of more than 1,600 travellers worldwide found 86% thought mini-bar prices were simply too high (rising to 90% for British travellers).
More than a third (34%) had been inaccurately charged for something in the mini bar or fridge and one quarter said they had had a dispute over their mini-bar bill when checking-out.
Just over half of those surveyed said convenience remained the main reason for using the mini-bar 51%.
Ian Rumgay, European communications manager at TripAdvisor, said: "Travellers are not at all satisfied with hotel mini-bars. Hotel proprietors need to think about reducing prices and introducing healthy options."
Favourite snack (in order of popularity) was nuts, chocolate bar, peanut M&Ms, Pringles and Toblerone.
Favourite drink (in order of popularity) was bottled water, fizzy/soft drink, beer, wine, spirits.
The most requested mini bar items were fruit, healthy snacks and sandwiches.
Unusual items found in mini-bars included bottled oxygen, sex kits, condoms, caviar and perfume.
