Welcome to planDisney, Holly!
When my daughter was younger, we would not return home until she had a hair wrap! So I understand how important this question can be. She loved returning to school with a section of her hair wrapped with fabrics and beading that she was able to select herself.
There are several locations that offer the hair wrapping service throughout Walt Disney World. On my last visit this past March, I noticed this service was offered at
Disney's Pop Century Resort,
Disney's Polynesian Village Resort,
Disney's Animal Kingdom Theme Park, and
Disney's Typhoon Lagoon Water Park. I did speak with a Cast Member and they were able to tell me that Disney's Port Orleans Resort - Riverside, Disney's Port Orleans Resort - French Quarter, Disney's Caribbean Beach Resort, Disney's Yacht and Beach Club Resorts, Disney's Grand Floridian Resort and Spa, Disney's Wilderness Lodge, and Disney's BoardWalk Inn also offer this service.
Holly, because the hours and availability are subject to change, I'd like to suggest that you stop by the front desk of your resort hotel to see if the hair wrap service is available at your resort. If so, the Cast Member will be able to let you know the specific times the vendor will be available. Otherwise, the Cast Member will let you know where the most convenient location is for you. Additionally,
Guest Relations should also be able to assist at any of the theme parks.
I hope you find this information helpful. Please let us know if there is anything further we can assist you with.
