just because you had some issues with RCI, don't assume your next Princess cruise will be as good as your last one.
I've spoken to a lot of people on a lot of cruises on a lot of different cruise lines. The one pattern that seems to come up over and over again is that the person's last cruise was the best, and the current cruise has a lot of disappointments. They loom large at the time, but then on the next cruise, the person looks back fondly at this one as the best one ever.
I don't think it's just a case of gaining perspective and blurred lines of one's last cruise. Sometimes folks fail to see the bigger picture of the vacation on their current or most recent cruise, and concentrate on what went wrong.
As for lobster, I like lobster, but honestly, I can't remember whether or not my last cruises had it on the menu. Of course, that may be more a function of my memory than my love of lobster.
