Thanks for the reply Rick. The only info I could find about the Diamond is the typical responses that some people write on cruise critic where they say everything was wonderful, the waiter was the nicest, the cabin steward was the best, etc.
It appears that the ship is very similar to the Caribbean Princess in layout which we did like except for the large number of people. The food on the CP was great, especially the Horizon buffet. We hated to see the IP go to Australia as we do like the smaller ships & there aren't many of them left lately- Even the Sun Princess which was in Florida for a good portion of the year is gone for now.
My wife enjoyed Hawaii so much last year that she talked me into it again.
If we lived on the west coast I think we'd be in Hawaii at least 2 times yearly on a cruise.
