Hi Vicki!
Thanks so much for stopping by the Disney Parks Moms Panel with your question.
Walt Disney World Resort's theme parks are filled with rides and attractions for all age levels, thrill preferences, and interests. While some
Rides and Attractions have restrictions in place when it comes to height requirements and health conditions, there are no specific restrictions when it come to weight. That being said, select ride vehicles may not be suited for certain body types.
I consider myself "fluffy", and there are certain restraints that aren't as comfortable as I'd like them to be! If a guest cannot safely fit in the ride restraints, it would not be safe for them to experience the attraction. Most of the rides with these types of restraints are considered thrill rides, and there is typically a "test seat" out in front of the entrance if a guest would like to test the fit before waiting in the queue line. Cast Members are very helpful in providing information about each ride, and will be happy to discuss options with guests if asked.
I hope this helps answer your question. Have a magical day! - Diane W.
