Mike & Charlotte,
My big complaint about the Tahitian Princess, though, and I'm sure it's the same on both the Pacific and all the others, is the showroom, and you didn't get into that.
When I was aboard the showroom, Princess's staff were drawing up a list of upgrades for the ship's next shipyard visit. The discussion at the time was that a major upgrade and reconfiguration of the show lounge was very high on the list. I don't know how extensive the actual upgrade to the showroom may or may not have been.
