Mikki, I stay at SSR often (it is one of my home resorts), so I will try to answer your questions. The preferred rooms are in the Springs area where the spa, main pool and restaurants are located or Congress Park, which is right by Disney Springs. I have only booked Preferred once and was in the Springs area. Springs is probably best with the wheelchair. All buildings in SSR have elevators. When Mom was with us, she didn’t have any issues navigating the room.
