I recommend that you rent a power chair for your cruise. It does not require anyone to push you and it gives you total mobilty on your own. They come with a power cord to keep them charged so you do not have to worry about a dead battery. It is a long walk or in your case ride from entry to the terminal to the ship and then to your cabin and when you disembark its just as long and you are normally tired from enjoying your cruise so much. The chair that I rent for my wife is compact and fit in the taxi drivers cab very easily. It also gives you the advantage to do things without your hubby...such as shop and sightseeing. The cost you will pay for the chair will definitly be minimal compared to the advantages you will enjoy, I promise.
