I have knee problems and walking any distance is difficult. They are now manufacturing small motorized scooters, light weight, and some of them even fold up. Do you know if cruise ships allow them and how you would get them on and off to explore cities visited.They weigh maybe 60-70 pounds.
as the other have said, have your TA find out for you. If it folds up you can store it in your stateroom, you would be responsible for getting it on and off of the ship, but there is always crew ready to help. Note: lots of the towns on the islands are not condusive for scooter travel, some have sidewalks some don't. They are usually very narrow, and bumpy. Do the go in the sand? this could be a consideration for the beach.
Just a comment - some of the $100-150 two wheeled scooters are not exactly considered "reliable" (at least the one I have). I procured an "Inop" scooter from a friend - upon dissasembly, I began to notice things like improperly heat treated structural hardware that strips out while applying torque (seat and handle bar rod clamps for example), poor electronic circuit board design, poor electrical connections (this was the reason I was offered this scooter for free after 30 minutes of operation from "new". She goes out with the trash tonight - looks like new though.
Here is the # to their Special Requirements office, they can help you out. My husband always brings his electric scooter, but you need a special room with a wider doorway so you can get it in and out...
