Yes! Most room reservations are refundable provided that you cancel before the hotel's cancellation deadline, which in most cases is within 24 or 48 hours of check in. If you have a reservation that's non-refundable, you might still have the option to cancel and be given a refund within a 24-hour period of booking. Add dates, click "Search", then you can filter by "fully refundable" to get the best options available near History Museum.
