Facts for the lockers INSIDE all 4 theme parks-
Rental for a larger locker is $7 per day plus a $5 key deposit.
Rental for a smaller locker is $5 per day plus a $5 key deposit.
When the key is returned, you receive $5 refund. (within 1 hour after park closes.)
Payment is made to a Cast Member who, in turn, hands you your key, so exact change or bills are not needed.
Using Lockers at more than one Theme Park in the same day:
Return key and receive $5 deposit and receipt.
Present receipt at next Theme Park and pay $5 deposit to receive key for the remainder of the day.
Depending on the crowd level, the lockers can be in shorter supply as the day passes.
If the park offers 2 sizes of locker and you want a larger locker, just ask the CM when you rent.
If they have any left at the time you arrive, you can have one. If no large ones are available, you'll just have to take the smaller size and "cram harder" OR rent two lockers.
OTOH, since many guests "park hop," there will be some lockers (large and small) that will become available throughout the day.
