Took my 84+ mother on this cruise. She is mostly in a wheelchair with some walker capability in room. We booked our room and then requested to be changed to a handicap accessible room a week before the cruise (concerned about chair maneuvering). NCL called the existing room holders who did not need the accessible room and had us switched-this was only the beginning of their great services to us. A bit of a confusion at embarkation due to this late change, but this was handled in stride by all. Once on board we found every level accessible and most things well set up for a handicapped person-a buffet is fun in that it gives many choices but usually not great for a walker/wheelchair-crew members were more than willing to walk along and help with the tray---restaurants were no problem (though East mets West kitchen can get a little overwhelmed if restaurant at full capacity-slower service and cold food can result-they will make it right though if you note this to the service). Moderna restaurant was our family's favorite in terms of flavor, hands down. Little things were all we could nit-pic...Fitness center could use a recumbent stride machine (like a nu step) as recumbent bicycles do not work with limited mobility joints as often seen in seniors. Make sure that the NCL shore excursion people are reminded about wheel chair accessibility the day before each tour so they can communicate this to the tour purveyor each time. When asked what her favorite part of the cruise was my mother said having all of the services provided in a helpful and solicitous fashion and the room and balcony which lent themselves to full mobility. That speaks to a real "vacation" . Thanks to NCL.
