Background: This was our first cruise with Process but our fourth cruise. My wife is in a wheelchair and we have experienced pretty good service from each cruise line. Princess was really no exception.
We were disappointed the reservations staff were not more knowledgeable about accessibility issues. We even had one agent tell us that this was not the cruise for those in wheelchairs, which was not true.
We were also very disappointed that Princess advertised a "wheelchair-confined tour" that implied it would be only for wheelchair passengers and a companion yet turned out not to be true.
Accessible room, including wheel-in shower. Elevators right outside the door but pretty quiet. Balcony overlooks two other decks of balcony's but no one overlooked ours. Ramp to the balcony made it nice but is difficult to use.
