These are all really good ideas, thanks!
Yes, I am a normally-sighted person, and will be traveling with a classmate ("D") that has low vision (I've never asked why or what specifically) and typically uses a cane because she says she has better far vision than near, but she was able to read our textbook on my computer if I zoomed the page in a bit. The other 2 of our group will be a partially blind husband ("J", he's albino, but again, I haven't asked if the low vision is due to that or what, I just ask questions about what they can/can't do and what they want help with) that uses a guide dog ("R"), and his normally-sighted wife ("V"). They've all been to Disney before, but it was years and years ago.
D has been watching
YouTube videos of some of the rides, and actually is excited about Toy Story. I mentioned that it's very vision based, but she doesn't care, she wants to experience it anyway. She doesn't think the ride part of the Living Seas will be good, or if she'd even like the aquarium part, but we're holding on to that if we need a cool off break. She's cool with all the coasters since they don't have big drops, and is still deciding if she's going to ride ToT. She wants to see Fantasmic, too, and possibly Philharmagic if the lines aren't too long. I never would have even thought about the moving walkways at the various rides, I'll have to ask her if she'd be OK with ones if they can't be slowed down or stopped. I've talked with her more about the trip than with the married couple because I share a class with her, and for the first 3 weeks of school she was without a cane because it had broken, so I walked her back and forth from the class we share. She moves around campus pretty quick, but I'm sure part of that is just the familiarity with the campus, so I don't expect her to be quite that fast moving at WDW.
We know that R won't be able to go on a lot of the rides, but will on some, and he rides well in a vehicle so he should be OK on the ones he is allowed on. If not he can use the kennel at the ride, or either V or me will sit it out. The only question J has is about AK, since he knows that guide dogs don't always do well at zoo type parks. I know there are a few walk through areas where you see the animals, which we will avoid (or they can go thru and I'll sit outside with R), and he won't go on Kilimanjaro even if he's "allowed" on it. Other than that, has anyone taken their SD to AK? Would you do it again? Or would you have left him/her at the park kennel for the day? I've downloaded the disability guide maps for all 4 parks so we know where the service animal "stations" are, and our coordinator is going to find out about getting us as close to the animal area at Port Orleans (speaking of, is there anything special we should ask for in the rooms?).
Neither of them are sure if they want to deal with getting the audio devices or not, because they don't know how helpful they actually are. We'll probably skip the parades since we're all "adults" and are more ride people than watching people anyway.
For on-property transportation, is there anything special we need to do? Is there a separate "waiting/loading" area for wheelchair guests that we would need to utilize? I know that D can handle a few steps (which I found out the say I completely didn't even think about it and led her thru the cafeteria so I could refill my water bottle before class and we had to go to down a flight of 4 stairs, eek), and will probably have to on the trip down depending on if we get a charter bus or if we rent 15 passenger vans, but I'm not sure about J. I think that having a few extra minutes to get on and settled out of the way before the other guests start getting on would be helpful, but I know they both want to experience the park as "normally" as possible.
