Hi Carol,
Thanks for visiting the Disney Parks Moms Panel with your question. I love
Disney's Old Key West Resort. It has such a relaxed atmosphere. I am sure you and your family will have a great vacation there!
Normal check-out time at Walt Disney World resorts is 11:00 a.m. You can request a late check-out at no charge for as late as 1:00 p.m. This is a request that you cannot make until after you have checked in, so wait until you are down at Disney's Old Key West Resort to do so. You could ask as you check-in, or call the front desk from your villa for assistance in making the request later in your trip. Late check-out requests are granted if there is availability. As with all requests, please note that Disney will do their best to honor them, but it is not a guarantee.
Also, Bell Services at the resort will hold your luggage for you until you leave for the airport. There are rest rooms located near the Hospitality House and The Main Pool where you can change clothes before you leave for the airport.
I hope that this information is helpful for you, Carol! Have a great time planning your vacation, and please do not hesitate to ask if you have any further questions.
