There is a video on you tube from all ears net, about visiting some of the resorts since the reopening and at one point near the end they show the inside of the buses from Disney Springs. The seats are numbered to let small groups of like 2 or 3 sit together, and of course some seats are marked don't sit here. It was the first time I've seen the inside of the buses since the reopening. Its about 45 mins long.
The interior buses are different style serving a different purpose than the Magical Express buses. I wouldn't expect there to be any similarity between the two, except maybe also some designated unavailable seats, for social distancing. But zones? Doubtful.
