I’m with @basp. I think it would make a great senior living facility, with some modifications. It isn’t like one person has to get a tiny Ritz Camera (or worse, a kiosk! lol) while another person gets an entire Macy’s. Divide the stores into rooms, maybe set up one of the anchor stores as a facility for people who need more assistance.
There could be an exercise room, a couple of community rooms for bridge and bingo. Access to public transportation would be excellent. The food court could be turned into the dining facility. Residents could come to visit and eat or they could have it delivered to their rooms. And, bonus, plenty of room and access for pedestrians, wheelchairs, walkers, canes and the ever-popular jazzy scooters!
I would love to live there!
Biggest issue I can see is lack of bathrooms. They can be added, but I’m not sure of the difficulty or cost of doing that sort of thing.
