I found this online:
Hair wrap stands are poolside at many of the resorts including Wilderness Lodge, Beach Club, Grand Floridian, Caribbean Beach and Port Orleans. There are also wrap stands on the Boardwalk, at Downtown Disney, and in the Animal Kingdom near the entrance to Camp Mickey Minnie.
We have done it on the Boardwalk and at the BC. The problem is that they all have their own schedules and not posted on the Boardwalk one when we have been there. We had better luck getting it done at the BC. You can easily walk around. We get there schedules and see which works in best. My DDs love it.
Enjoy!
