We're staying onsite, but was wondering if any of the water rides have lockers by them. I don't want to miss these rides, but I don't want have to take the time to go back to the room to change into dry clothes. I was hoping to wear a backpack with a change of clothes that I could put in a locker when I go on a water ride, like the rapids at Animal Kingdom or the log ride in Magic Kingdom. Are there lockers near the water rides to store a change of clothes? And for that matter, are there lockers by many rides to store a backpack while you actually ride the ride? I'm assuming you can't take a backpack on the rollercoaster and other rides. Thanks for any help!
