Marilyn,
Thanks for asking your question to planDisney!
Depending on how large your son's luggage is, he might be able to head straight to
EPCOT to join you on your day there.
The theme parks and water parks have
lockers that can be rented for the day. They are one of the most overlooked conveniences available at Walt Disney World. It would require him to go through the security at the park before he can reach those lockers at EPCOT, but as long as that is not an issue, this might work!
The lockers in each park can be found just after passing through the turnstiles, and there are a few locker sizes available.
Disney's Hollywood Studios and
Disney's Animal Kingdom Theme Park, as well as the two water parks, have lockers that are as large as 15.5" x 13" x 17" (39.37 cm x 33.02 cm x 43.18 cm). The
Magic Kingdom Park and EPCOT even have a few jumbo-sized lockers available that are up to 17" x 22" x 26" (43 cm x 55 cm x 66 cm). By my estimate, that jumbo size will fit many carry-on bags, but he can measure it out ahead of time. So, if that larger locker size at EPCOT will cover his needs, then he should be good to go. Otherwise, he would need to head to the resort hotel first, where he can quickly drop his bag off at the Bell Services desk to pick up upon his return.
BONUS TIP #1By the way, the lockers are keyless, so you don't have to mess around with that, either!
BONUS TIP #2The lockers can be used throughout the day for that one-time charge. You can go back to the locker to retrieve something, and then use it again on the same day without having to pay again.
Please feel free to
write me back directly if you have any follow-up questions.
Have a Magical Vacation!Doug
