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