My mom is wheelchair bound and can't transfer out of her power chair (also has MS). She isn't able to ride this any longer. However, over the last couple of years, there have been more rides that she is able to get on without transferring. The coolest one is the Jungle Cruise - which I never thought she would be able to do. This was always her favorite ride so it was so cool that she could do it.

Hopefully your wife will find many other rides to keep her happy. Enjoy your trip!
