Hi Elizabeth,
Thank you for visiting the Disney Parks Moms Panel with your question. Your trip is coming up so soon - you must be getting excited!
There are salons at Walt Disney World that should be able to provide hair services for your daughter. These include
Ship Shape Massage - Salon - Fitness at Disney's Yacht Club Resort, the Ivy Trellis Salon at
Disney's Grand Floridian Resort & Spa, and
Casa De Belleza Salon at Disney's Coronado Springs Resort. These salons can work with children, and may be able to do a child's updo. You may also want to look into the
Perfectly Prepared Princess Package at these salons, which offers varying levels of services for children, some including hair, makeup, and manicure. In order to book either a hairdo or the Perfectly Prepared Princess Package at any of these salons, you can call (407) WDW-SPAS (407-939-7727). Be sure to indicate in either case what kind of hairdo you are wanting for your daughter, and the cast member will be able to note this on your appointment.
I hope that these ideas are helpful for you, Elizabeth. Have a wonderful time planning your magical vacation, and please do let us know if you have any further questions.
