I cannot answer all of your questions, but if it is just the two of you in the studio and the sleeper couch is not out, there will be plenty of room by the bed for his chair. It did not have a large or heavy coffee table and was easy to move. With the couch out, the chair could be at the foot of the bed, but not enough room to be next to it. As for TOTWL, like all BLT guests, there is the one elevator that gets you up to the top. I think there were both steps and a ramp built there for all guests, but that is just memory and may be wrong. It was a short walk to MK. Once you get to the end of the parking lot, you cross the street at the light, and essentially, are where the buses pick up resort guests (other side). As for dedicated walk, i don't think there is one, but that should nit be an issue. You have the sidewalk and exit road from BLT to street, and then on MK side, it is a large walkway. Have a great trip.
