Hello Sarah,
Thank you for visiting us here at the Disney Parks Moms Panel with your question. I hope you are having a magical day.
It seems like Fozzie Bear and the rest of the Muppets from Muppet*Vision 3-D may be backstage somewhere writing sketches and jokes. Muppet*Vision 3-D closed this past January for the show ”For the First Time in Forever – A Frozen Sing-Along Celebration" to glide onto the stage. However, there have been no new announcements whether Muppet*Vision 3-D will return or another exciting experience will may its way to the theater.
I like to keep an eye on the Disney Parks Blog since they always are the first to let us know about exciting news regarding Disney Parks.
As far as wheelchairs, Hakuna Matata. The Disneyland Resort has
wheelchair and ECVs available for rent for use in both Disneyland Resort theme parks. Here is some information
regarding attractions for Guests with Mobility Disabilities including those that allow Guests to remain in their wheelchairs or ECVs, those that require Guests in ECVs to transfer to wheelchairs to board and those that require Guests to be mobile to enjoy.
I hope this helps you. Please feel free to visit us again with any other questions you may have.
Wishing you magic!
