He has one at home that he uses sporadically. It'seasier for us to rent one down there instead if dealing with it on the plane. He has major balance problems so standing in a line (however short) isn't a great idea. He's also prone to fainting as well. Ill just go to guest services explain it all and they'll tell me if he needs one or not. I really appreciate all the help and info! I get major crowd panic attacks and having an alterate place to wait is the only way to keep me from major meltdown. We make quite the pair!
If he has major balance problems, then he MUST have a wheelchair. If he has fainting problems, I worry about him in an ECV.
Most lines in WDW are mainstreamed, so from what I have heard about him, you will definitely need a wheelchair or ECV for him. There is no GAC to shorten wait time, and there definitely is no GAC to shorten the amount of distance covered.
Something to consider is what the GAC (no matter what stamp you get) does NOT work for:
Character Meet and Greets
Parades (there are wheelchair viewing areas, but no guaranteed benches)
Fireworks (there are not even wheelchair viewing areas)
Restaurants
Stores
Buses - waiting for them, boarding them, etc
Anything at the resort
Street Shows (Dapper Dans, Flag Retreat)
Fantasmic (though there have been varied reports)
Illuminations (you may access a wc viewing area but there are no benches)
Parking
Monorail
Transportation Boats
So basically unless you are on a ride or in certain shows, the GAC is not going to help at all. If you plan on riding the bus, you will REALLY want to have a wheelchair for him - otherwise he could end up standing!
This is not to say not to ask at Guest Relations about a GAC for one or both of you, but you do need to know that the places a GAC is accepted is limited, and in no way would guarantee a shorter wait, shorter distance (just the line into Soarin alone is 1/4 mile - and that does not include the 3/4-1 mile to get into the Land Pavilion and up the hill!), or a place to sit.
