I totally agree. My daughter in law has a fold up scooter for trips etc and finds it invaluable. One problem it does not like hills-good job there aren't any on a cruise ship. I have recently been on a NCL cruise and a wheelchair had fallen over during the night in the corridor blocking three quarters of the corridor, which is no good in an emergency. we did pick it up of course. YES I am totally behind the decision to limit the size as this does not stop the passenger from having a really enjoyable cruise,
