If you drive and have a car available then you have no problem, if you don't have a vehicle there are others available or you can use the Gondola's, but, you don't have too. No one is going to be standing in the lobby with a rifle forcing you to use them. It is strictly your choice. At this point, you can take the Gondola, if you have a car you can take that, which is something that it sounds like you do anyway, use a Minnie Van or not stay at a Gondola Resort. Phobia, although a problem for the people with them, are not considered a handicap and are not covered under ADA.AOA is already priced higher than moderates. I'm going in April and it was priced higher than all the moderates.
I know this isn't just me because it's a common phobia, but I'm terrified of heights. I stopped skiing because I won't go on chair lifts anymore. I wouldn't get on this thing for anything.....that said we drive to the parks from our hotel because we had terrible experiences with busses and even monorail before. We love the boats though. I just wonder if Disney took into account how many people have a serious aversion to heights?
Realistically, if any company had to provide options for all the possible phobia's in the world, all the places like WDW would close up. It wouldn't be possible to modify for every possible scenario. And it is really not realistic to think that Disney will make water connections between all those resorts and the two parks. That's asking to much when one does have options even if it isn't buses. All the laws insist on is that people have access, everyone has access, I go to WDW all the time and do not have to do any of those things if I don't want too with the exception of MK. In which case you have to use the Monorail, the ferry's or a resort bus. (or a Minnie Van) I don't know if the Minnie goes to the front gate. Someone else might know the answer to that.
