A five y/o would not be allowed to stay in the child swap room by himself. We actually saw this when we were there May 12th. We were going to leave my 79 y/o mom there, while we rode. The TM told her she could either go into the child swap area to wait or she could sit in the wheelchair and wait for us right outside that area next to the elevator. Anyway, while we were dealing with her, we heard a lady arguing with a TM about leaving her kids in there. They looked to be about 5 y/o and 6 y/o. The TM was telling her they could not be left without an adult to supervise them and she kept arguing that they'd be fine in there until she rode the ride. The TM just kept telling her kids were not allowed in the child swap area, without an adult being with them. I'm not sure how she got through the line with them, unless the other TM's just assumed she was with another guest.
