Hi Raika,
Welcome to the Disney Parks Moms Panel and thank you for asking us a question, my fellow Canadian!
I’m happy to say that, even if you’ve already checked out of your room at a
Disney Resort Hotel, you can still continue to enjoy all of its amenities until the clock strikes 12 the day that you’ve checked out. This means that you can absolutely still use the pool at your Resort while you wait for your ride to Orlando International Airport aboard
Disney’s Magical Express or whatever other transportation you may have arranged for the end of your stay.
From what I understand, towels, a shower and even lockers are available at the pool area of
Disney’s Caribbean Beach Resort near the Fuentes del Morro pool. Don’t forget that you can also store bulkier items with Bell Services and have them hold your things until you leave.
I hope my answer helps you plan a smoother (and splashtacular!) departure day during your upcoming vacation. Please don’t hesitate to come back and see us if you have any other questions.
Have a Magical Day,
Lynne
