Yes! Most hotel reservations are refundable provided that you cancel before the accommodation's cancellation deadline, which in most cases is within 24 or 48 hours of your scheduled arrival. If you have a reservation that's non-refundable, it may still be possible to cancel it and be given a refund within a 24-hour period of booking. Add dates, click "Search", then you can use the "fully refundable" filter to review the best options available near Planetarium 1.
