Hullo, I have travelled on Princess and PO lines and I can say that the disabled facilities are the best I've seen. Admittedly I am thankfully notdisabled butn I have spoken to a number of wheelchair users on board. They nhave all said that access was good. They have rooms with msider doors, bathrrom facilities and they provide designatied access when going ashore. On our last trip on Princess to the Caribbean we even met a blind couple with guide dogs and they said they have travelled several times on a boat. Princess provided them with 'helpers' during their stay. You havent said exactly your disability but I centrally wouldn't let it stop you from enjoying a fantastic holiday. Do need to book early to get the larger adapted rooms. Good luck.
