Yes! You'll find that most room reservations are refundable provided that you cancel prior to the hotel's cancellation deadline, which in most cases is within 24 or 48 hours of your check-in date. If you have a reservation that's non-refundable, you may still be able to cancel and be given a refund within a 24-hour period of your booking.
