They will ask you if you want to transfer or remain in the chair etc. We got there pretty early once and I got the last wheelchair place for our show.
Another time I did transfer out but I told them I cant do alot of stairs etc, so I think we got the 2nd row from the wheelchair seating. Then they still kept asking us to move. I think I told them I wasnt moving any more. We ended up by the sign language interpreter, which was interesting.
I am planning on just staying in the wheelchair in dec. since it will only be dh and I.
