Are there lockers big enough for a small carry on suitcase anywhere on the park? What would be the biggest dimensions?

The large lockers outside the rides can fit only laptop bags.. I am not sure if they have anything else.. pls chk with them

There are large all day lockers. Ask the staff or call. They won't let you go through security with luggage, but if you have a bookbag that's fine.

The free lockers are small like a 20x10x50 and payed lockers are little bit bigger. I didn't see any bigger lockers!
