How much is it to rent a locker for all day?

I believe around $15. But you can rent them at each ride and it's $1/ per hour some rides are in the same general area and renting a locker for $2 for 2 hours should be plenty of time in those areas. :)

Some rides u can bring bags on others have areas where u can use the lockers for a couple of dollars we did this as then your bag is close if needed instead of walking back to ftont of park

Yes what Jackie said

20 -30 or 40 depending on the size
