Hi Arthur!
Thanks so much for stopping by the Disney Parks Moms Panel with your question.
Standard Walt Disney World Resort
theme park tickets provide admission to one theme park per day for each day of your ticket. With the addition of the Park Hopper option, guests can enjoy same-day admission to all four theme parks (
Magic Kingdom Park,
Disney's Animal Kingdom Park,
Epcot, and
Disney's Hollywood Studios) on each valid day of the ticket. Walt Disney World Annual Passholders also have the ability to "park-hop" with a valid Annual Pass.
On one of our last Disney vacations, my daughter and I actually "hopped" to all four parks in one day! We were exhausted by the end of the evening, but we made memories to last a lifetime.
I hope this helps answer your question. If we can be of further help as you plan your Walt Disney World Resort vacation, please let us know!
Have a magical day! - Diane W.
