I think I read somewhere that there are lockers located near the water rides so that you can stash things you don't want to get wet -- and that the lockers were free for like the 1st hr. I did not notice these last time we were there. Whereabouts are they? Are they free? Can we take backpacks on all rides (except for roller coasters)? Seems to me I had read somewhere that back packs were not allowed on any rides. Trying to figure out if it is feasible to switch between sneakers and water shoes for various rides (don't want to wear water shoes all day in the park)
