Yes! You'll find that most room reservations are refundable provided that you cancel before the hotel's cancellation deadline, which is often 24 or 48 hours before your arrival date. If your reservation is non-refundable, it might still be possible to cancel it and be given a refund within a 24-hour period of your booking.
