Hi Christine! Welcome to the Disney Parks Moms Panel.
My family always reserves a later flight on our departure day so we can squeeze in every last bit of Walt Disney World Resort magic before heading to the airport.
Suitcases and bags larger than 24" x 15" x 18" are not permitted in any Theme Park. While
lockers are available at Disney's Animal Kingdom Theme Park, the largest lockers there are 15.5" x 13" x 17". There is currently no bag check option at the Theme Parks for larger items. You don't mention where you are staying or what transportation method you plan to take to the airport, so I'll give you a couple of options.
If you will be using
Disney's Magical Express complimentary airport transportation, your motorcoach will depart from your Resort Hotel. Bell Services can hold your bags until you depart. If your flight is on a participating airline, you may check your bags through to the airport at the
Resort Airline Check-In desk before heading out for the day.
When my family rents a car for our vacation, we load it up with our luggage before going to the Theme Parks, and depart for the airport straight from the parking lot. If you will not have a vehicle but would like to rent one for this purpose, you may reserve a one-way rental from the
Car Care Center at Walt Disney World to Orlando International Airport.
Christine, if I have not addressed your particular situation, please feel free to write us back. Enjoy your stay!
