Hey there, Shelia!
Walt Disney World Resort transportation is one of the absolute best parts of a Walt Disney World Resort vacation. As a mom of little ones, I really love having stroller-friendly transportation to whisk me away to the parks.
Shelia, the answer to your question is "it depends." If you are at a Walt Disney World Resort theme park and wish to head to a nearby resort hotel for a lunch reservation, you are absolutely able to. What you are also able to do is to use Walt Disney World Resort transportation to hop from one theme park to another, provided you have a
Park Hopper ticket, of course.
You may encounter an issue with getting to the source of Walt Disney World Resort transportation. You will need to have a dining reservation to park at any
resort hotel, and you may only park for 3-hours, so you will be unable to park at a Resort hotel and take a bus to the theme parks. Likewise, busses do not go from central locations like Disney Springs to the theme parks.
I hope that this answered your question, Shelia!
See you real soon!
