The cancellation policy varies depending on the hotel and the type of reservation you make. Many hotels have a flexible cancellation policy that allows you to cancel or modify your reservation without any charges up to a certain deadline, which is usually 24 to 48 hours before the scheduled check-in time. However, some hotels may have non-refundable or stricter cancellation policies, especially for discounted or special rate bookings. It's important to review the hotel's cancellation policy at the time of booking to understand any potential charges or restrictions.
