My friends just got back from WDW, and their day at AK was ruined because they got totally soaked on the Kali River Rapids ride early in the day. They were then chilly, uncomfortable, and finally left the park early so they could change. This would definitely ruin my day as well. Has anyone brought a change of clothes just in case, and stored them in a day locker? Are the lockers near the entrance, and does anyone know the cost of a day rental? Thanks for your help!!!
