Welcome to the Disney Parks Moms Panel Nikki ~
Your trip is just around the corner and I bet you are too excited to sleep!
It is great to see that you are planning ahead for your trip. That will make it so much smoother once you arrive at the Walt Disney World Resort. Disney World does a great job of providing
services for Guests with mobility disabilities. Most of the queues are now wheelchair accessible and you can remain in your wheelchair while waiting. For some of the attractions, you will remain in the regular queue until you reach a certain point and then a Cast Member will assist you to an alternate loading area to board the attraction (for example Kilimanjaro Safaris and Buzz Lightyear's Space Ranger Spin). There are a few that still have alternate queues for Guests in wheelchairs and a Cast Member will direct you to the alternate queue. Big Thunder Mountain Railroad in the Magic Kingdom is one of those.
Most attractions will allow Guests to remain in their wheelchair until boarding. A Cast Member will move your wheelchair for you and they will have it waiting for you at the end of the attraction. Some attractions have ride vehicles that will allow Guests to remain in their wheelchairs. The link I've provided above will list those.
Some attractions have a moving sidewalk in the loading and unloading area. Take your time and don't feel rushed. If you need the moving sidewalk stopped or slowed down, just ask the Cast Member before you step on. They can slow down or stop most (not all) of the moving sidewalks to assist you if you need additional time. They cannot slow down or stop the moving sidewalks on Peter Pan's Flight or the Tomorrowland Transit Authority PeopleMover so keep that in mind.
Please feel free to visit us with all of your planning questions. We are hEAR for you!
Wishing you minnie magical memories :-) Allison V.
