I did speak with Director of Disabilities Services about Runaway Railroad and was told the ride manufacturer determines whether or a vehicle can have a WAV. The manufacturer didn’t even OK RR to have a transfer access door, so it has a transfer assist device (transfer tier) that can be attached to the ride car, but there is still a very small opening.
We rode RR with our wheelchair using DD and found it not easy to lift her in and out. We expected some spins/etc. maybe similar to the quick turns on Toy Story Mania. We felt all the motion was a lot more than that and could see why no wheelchair car after riding. I think it was
@KPeveler who posted the same.
Having now ridden Remy, Rise of the Resistance and RR, DD felt least secure on RR
