It's possible but you must request it at the front desk. If the hotel has the availability for a night stay, then you will simply be asked to pay for the supplemental nightly rate. Essentially, a day room is guaranteed for the hours listed on our platform, which have been extensively negotiated on your behalf. Any changes to the booking times are subject to the hotel's confirmation. Please note that if it weren't for HotelsByDay, the only other early check-in alternative would be 3 p.m.
