Whether you can cancel a "HotelTonight" reservation depends entirely on the specific terms shown at the time of booking, but the general rule is no. Most rooms on HotelTonight are offered at a deep discount because they are non-refundable, non-cancellable, and non-transferable. These "Last Minute" and "Daily Drop" deals are final sales. However, in 2026, some hotels on the platform have begun offering "Flexible" rates for a slightly higher price, which may allow for cancellation up to 24 hours before check-in. If you made a mistake during booking, you must contact the hotel directly immediately; while HotelTonight’s support can advocate for you, the final decision to refund a "non-refundable" room rests solely with the hotel management. To avoid being "stuck" with a room, always double-check your dates and location on the map before swiping to book, as the platform's user interface is designed for speed and "one-swipe" confirmation.
