We have just disembarked the Diamond Princess, (cruise no: M331)
For the most part it was a great experience, we met some really good people, our cabin was amazing, the ports of call were great, some tours were not as good as some, could of had a little more choice.
The embarkment process was smoothe, as was disembarkment, and for a ship of that size that was impressive.
Fantastic room, great size balcony, the above cabins are able to look down on you but it was not a problem at all.... We would get this catergory again for sure.
