EARLY CHECK-IN
You can register as early as 7:00 AM at any Disney Resort. While the room may not be ready at that time, you may complete the rest of the registration process. You will receive your Resort Key to the World (KTTW) Cards with your Theme Park tickets, dine plan, room charge privilege and any other included package components encoded on it upon registering.
If your room is ready, the front desk will be happy to assign it to you early. If your room is still being prepared, you will be given a phone number to call to find out the status of your room availability. Once you are told your room is ready, you will not need to return to the front desk. Your KTTW card will automatically be activated to open your guest room door.
While waiting for your room availability, feel free to give any luggage you may be carrying to Bell Services and start enjoying your Resort's pool or other amenities or hop on the resort transportation to visit any of the Theme Parks or Downtown Disney.
LATE CHECK-IN
If a Guest has a deposit on the reservation, the Resort will hold the room until check-out the following day.
LATE CHECK-OUT
Late check-out availability is limited. Requests for late check-out can be made at the Front Desk any time after arrival. There may be an additional charge for a late check-out based on the time you wish to vacate your room.
