I know the parks have lockers where you can lock your stuff up, but how big are they? For example, if we bring our folding bag chairs into the park to use for watching fireworks, are the lockers big enough to store them? Or do I just need to run back to the resort to get our chairs closer to time for fireworks? How much do the lockers cost? Is it a one time, all day fee, or do you have to drop in a quarter or two every time you open it and close it again (like at Sea World)?
