I was reading the discription for the Atlantis Tour and it says "This tour is accessible to guests with limited mobility; however, guests must be able to climb into the coach and take a few, small steps on their own." Does anyone have any input on if this is still a issue ? The problem is my son is 17 and in a wheelchair and he cant climb or walk (even a few steps) . Ive been told the tour at Atlantis is great but is the vehicle doing the transporting doesn't have a lift ill assume we wont be doing that.
