My wife and I stayed on board for 2 cruises; these were our 14th and 15th cruises, our 4th and 5th cruises with Princess, but the first two on Diamond Princess.
The Ship
It was very clean and had a relaxed atmosphere, 1,600 passengers on the first cruise and 2,600 on the second cruise, on the second cruise most of the passengers appeared to be Japanese.
B735, the cabin is in a good position, fairly quiet because it was at the back of the boat away from the lifts and had cabins above and below it.
