Years ago, when I used to visit Walt Disney World with my extended family, we would have given anything to be able to take Disney’s bus transportation from one theme park straight to another one without having to switch in between, but such a thing did not exist.
Guests who have Park Hopper tickets can visit one theme park in the morning, and then, beginning at 2:00 p.m., they can head to a different theme park.
Starting at 1:30 p.m. daily, Disney’s free transportation offers park-to-park buses that will whisk you off to your afternoon/evening theme park destination.
It’s important to remember that you must have a Park Pass reservation for the first theme park you’re visiting on any given day.
