Our son who's 43, college grad, drives a car and woks full time as an instruction assistant in special ed in the high school have a big accessible room. The room connected to ours but with a narrow doorway he was unable to enter our room either through the connection or the main door.
Also there was not a single handicapped bathroom (men's) that he could use.
Otherwise a very nice fun cruise for all 18 of our family (nine grandchildren ages 3-17) and our children and their spouses.
Loved being 'inside' on 14th floor with ocean view out the back of the ship...and an opportunity to see the Aqua Theater show from our balcony. Very quiet rooms with some notice of outside activities in the evening. No problem though.
