1. To start at the beginning: I have cruised many times with small and large vessels I have never had trouble stepping in to a bathroom. The first thing I noticed was a bathroom raised up far more than any other I recall making entry with a knee replacement ver very uncomfortable
2. I use a very small and portable rollator (Spry). The Maitre D of the dining room made certain I knew that the dining room was not (I don not remember exact words but "ADA compliant)
3. The Nautica prior to booking or during the process never told us that the itinerary and ports of this cruise were very "rigorous" and not quite appropriate for a disabled individual, even though they knew I walked with a rollator
4.I had chosen to have private drivers in many ports so can not comment. I can say that Santorini involved a climb up about 18 stairs to a cable car to get to town The town was a very steep donkey trail. No cars can get in. Donkeys are used to move merchandise. On this kind of cobblestone I had to push my rollator
5. Rome is a separate issue.
I had gotten permission in advance to join the tour to the Vatican. We had cleared everything in advance.
We got to the bus to go to the Vatican, my rollator was stored. I had just gotten on the bus, my son had not, when some lady barges at me telling me I could not go on this bus, I could not go on this tour, that she was not going to watch out for a disabled individual, that I should get off the bus and I would not get my money back!! (PS I dont need anyone "watching out for me)
6.The morning of disembarkation I got my foot stuck (again) in the door to the bathroom.when I went to wash up. I was in pain and sat down to try to extricate myself..I yelled for help.. skip to the final behaviors of the crew: They must have come in to the stateroom when hearing me ... I found myself lifted up and placed on a wheel chair, dressed by someone and then carried down the gangplank and placed on the warf with our luggage. I heard people telling us never to come back on the Nautica that it was a ship for people to have fun, not disabled and sick people
