Hello again, Rosilyn!
Thank you for asking another question to the Disney Parks Moms Panel! You will find
Locker Rentals in all four theme parks, and they vary a little in size and price.
There are key-operated lockers in each theme park, which can be accessed all day for a one-time fee and $5 refundable deposit. These key style lockers are available in two sizes: small (11" x 9" x 16") and large (17.5" x 12" x 16").
Single-use, coin-operated lockers (quarters only) are located near the bus information booths at Epcot and Disney’s Hollywood Studios. Although Hollywood Studios offer two sizes (12” x 24” x 28” and 4” x 5.5” x 6”) the ones at Epcot are a little larger (23” x 16” x 29”).
Be sure to check the dimensions of your walker once folded to see which type of locker may be your best option. Please note these are current prices and subject to change without notice. Also, lockers rentals first come, first-served basis and reservations not accepted.
Wishing you a vacation full of magical memories!
Missy
