Yes, the majority of hotel bookings are fully refundable as long as you cancel before the accommodation's cancellation deadline, which often is within 24-48 hours of check in. If you have a reservation that's non-refundable, it might still be possible to cancel it and get a refund within a 24-hour period of booking.
