Again, these types of facilities cannot be segregated. You can’t have a group restroom with a wheelchair accessible stall, even if there is a wheelchair accessible restroom right outside. You cannot have the wheelchair accessible section in a theater. You cannot group all of the different accessible hotel rooms in one part of a hotel.
Forcing a person to be alone is a separation. That’s why venues have to have companion seats, so that a disabled person isn’t forced to be alone. That companion doesn’t have to be a caregiver, it can just be a friend.
