I use an electric wheelchair full-time and can't sit up without complete support. Our last trip to Disney World I spent about 10 hours researching wheelchair accessible rides. I didnt transfer for any rides and still had a fantastic time.
When the map says
ECVs must transfer-it is talking about the 3 wheeled scooters or the chairs Disney rents NOT electric wheelchairs. Here is a list of rides that you can drive your wheelchair directly onto without transferring, sorted by park:
Magic Kingdom---
Buzz Lightyear's Space Ranger Spin: (note-this ride doesn't fit all electric chairs--my standard Invacare Action electric wheelchair didn't fit-and the shooter is hard to reach, especially with contractures)
Stitches Great Escape (note-the bars that come down on the shoulders could be painful, especially if they are drawn up like mine-I havent ridden it-this ride has got a lot of bad reviews)
Many Adventures of Winnie the Pooh (Takes you through several classic scenes-awesome-easy access)
its a small world (easy access)
Liberty Belle Riverboat (Tour around a lake with some props and animatronics-kinda long-chair sits below level of bars, partially blocking view)
Main Street U.S.A.-Railroad-steam train ride (I loved it. Round trip is best, there are scenes along the way. I am not sure if all stops are accessible so get on at Main Street)
Jungle Cruise (recently converted)
The Magic Carpets of Aladdin (too short for some chairs)
All the Character Greeting Areas and shows are wheelchair accessible. There are always spaces for wheelchairs with seats for family members adjoining
(Storytime with Belle, etc. all children sit on the floor up front)
Swiss Family Treehouse and Tom Sawyer Island are impossible for wheelchairs (you can do a roundtrip on the raft that goes to Tom Sawyer Island)
All night-time shows and parades have special wheelchair viewing areas-ask a CM, they're marked on a map- arrive 1-2 hours early for a seat and you cannot leavenighttime shows are my favorite and are well worth the wait
Shows I recommend:
Time Keeper (360 degree imaging with awesome Animatronics that take you on a time-travel adventure fraught with danger and comedy *may be gone)
Carousel of Progress (the classic tale following an animatronic family through different eras of invention)
Enchanted Tiki Room (Under New Management by Zazu and Iago creating a cute, funny adventure-mild danger- with special effects.)
Philharmagic (3D show-which are always awesome-I like it just from clips Ive seen)
Spectromagic parade (nighttime parade of lights)
Wishes Fireworks (replaced Fantasy in the Sky-I have heard it is incredible and already love it from the pictures and video clips that Ive seen-mixing lasers, beautiful fireworks, and heartwarming character narration).
Epcot
Ellens Energy Adventure (easily accessible-cute Jeapordy style beginning that then takes you back in time to Dinosaurs)
Journey Into Your Imagination (easily accessible-really cute/fun ride with a fully accessible interactive special effects playground afterwards)
Living with the Land (informational tour about various climates and agriculture)
El Rio Del Tiempo (accessible-boat ride tour of Mexico)
The Living Seas (all areas accessible, although some areas may have alternate access. At your own pace viewing of a live sea aquarium and the new Crush attraction)
The World Showcase (all areas accessible, although some areas may have alternate access)
Street shows are hard to see unless you arrive a little early to sit in front
All the Character Greeting Areas and shows (including Innoventions) are wheelchair accessible (*note: The Kid cot fun stop crafts will be difficult to do unless you have a tray on your wheelchair because the table and chairs are low and the supplies are scattered)
All night-time shows and parades have special wheelchair viewing areas-ask a CM- arrive 1-2 hours early for a seat and you cannot leave-- nighttime shows are my favorite and are well worth the wait
Shows I recommend:
Honey! I Shrunk the Audience-3D (awesome multisensory adventure with a 3D movie as well as a moving stage-you can feel the effects while in your chair-and incorporates the feel sense)
Cranium Command (funny and cute story that portrays the job of a brain pilot that tries to control the different organs/body systems of a 12 year old boy throughout his day-really funny *may be gone)
Some areas of Innoventions are fun. You can build a robot and keep it for free.
Illuminations: Reflections of Earthincredible nighttime show with lasers, fireworks, music, and a global earth ball promoting harmony through a heartwarming, fantastic display.
MGM Studios
Great Movie Ride (note-this ride doesn't fit all wheelchairs-my standard Invacare action electric wheelchair didn't fit and I had to ride sideways)
All the Character Greeting Areas and shows are wheelchair accessible
Shows I recommend (MGM has a lot of good shows):
Indiana Jones Epic Stunt Spectacular (live action awesome show)
Sounds Dangerous (special show that relies almost completely on hearing with incredible effects * a lot of parts in complete darkness)
Voyage of the Little Mermaid (play type show with characters, puppets, props, laser lights, and occasionally a fine mist to create the effect of being underwater. A great place to cool off)
Muppet Vision 3D (cute 3D show with feeling thrown in through water sprays, etc. The pre-show is also good)
Beauty and the Beast- Live on Stage
All night-time shows and parades have special wheelchair viewing areas-ask a CM- arrive 1-2 hours early for a seat and you cannot leavenighttime shows are my favorite and are well worth the wait
Fantasmic-(The best nighttime/overall show. Note: Use the wheelchair seats in the back and arrive 2 hours to get a good seat)
Animal Kingdom-
Wildlife Express Train (train that shows you how Disney cares for their animals and takes you to the Conservation Station-may have to back on)
Triceratop Spin (note: I never rode this ride and I am not sure if it accommodates electric wheelchairs or just manual ones)
Kilimanjaro Safaris (mild thrill ride with a guide that drives you through authentic habitats to view real exotic animals-best experienced in the morning. Note: This ride is bumpy. You may need to back in to the ride vehicle.)
All the Character Greeting Areas and shows are wheelchair accessible (*the Boneyard is not. *Conservation is listed as accessible but I didnt visit it.)
All the nature trails are accessible and have beautiful wildlife. There are many exhibits-a few viewing areas are a little difficult to get to.
All night-time shows and parades have special wheelchair viewing areas-ask a CM- arrive 1-2 hours early for a seat and you cannot leavenighttime shows are my favorite and are well worth the wait
Shows I recommend:
Festival of the Lion King (ties with Fantasmic for best show-Incredible show with acrobats, fire blowers, animatronics-cannot miss)
Its Tough to Be a Bug-3D (multi-sensory show with animatronics as well as a 3D show. Note: a few effects will be missed if youre not sitting in a chair, but I never transferred and fully enjoyed the show-one of my favorites)
Flights of Wonder (bird stunt/aerial flying)
I only transferred to rides when I was younger and stronger. The last trip I didnt transfer to any rides and still had a fabulous, magical trip with the plentiful wheelchair accessible rides and awesome shows. Always carefully weigh out the risks of transferring.
I hope I helped.
Remember all shows are wheelchair accessible-don't miss the nighttime shows-especially Fantasmic-and don't miss Festival of the Lion King.
If there is anyway she can transfer, I would do it for Soarin in Epcot. The ride is awesome. Even I was able to do it. You can pull your chair right up to seat and the movements of the ride are smooth.
Have a great trip!
