I would call the theater first. Their customer service is really good. They are very accommodating. The seats are so comfortable. Definitely have to take advantage of trying out the seats...heated and reclining.
She can be in the companion seat with the empty wheelchair next to her. The seat is a reclining seat, so I think the best best is to buy the companion seats near the space for the wheelchair. That way you don't have to fold up the wheelchair.
