I can’t speak to the cabin situation since we have never used an accessible one, but I will say that we have taken two cruises with my husband using a rollator walker. Both on Holland America. I felt that they were very accommodating to those with walkers, wheelchairs and scooters. After we were thru security we immediately directed to a very short line for check in for special needs only. Then the wheelchair waiting area was right beside it. Boarding wheelchairs are limited, so we waited our turn. The steward arrived with a chair and there was a couple who had their own chair and they were asked to walk with us and we all rode the elevator together and then straight onto the ship. In our case we were taken straight to our room. We found that there were many, many scooters, wheelchairs and walkers on our two Holland cruises. There was a special area reserved for wheelchairs in the main theatre. I found that the guests on Holland tend to be a little older than other cruises we have taken. On a Carnival cruise sometime ago I noticed many people pushing past wheelchairs, scooters etc to get on elevators. I never saw that happen on Holland. People were always nice and allowed us to go first when my husband was using his walker on Holland. He took a fall while I was in the spa and said many people came to help, staff and guests. A staff member helped him back to his table and doctored his elbow which was bleeding. It was a little crowded in the buffet, but the wait staff was helpful finding us a table and getting our drinks for us. Many videos on YouTube you might be interested in.
