Oh my gosh, I would have to vote that if a merger is a must, that Princess will merge with RCC and bring the best of both lines together.
Carnival has such a reputation for sloppiness, party ship, poor food, roudy crowds.
We loved the Grand Princess ship last summer and were happy with the Rhapsody this summer, but wished our group would have traveled on Voyager.
RCC still has the best food, but the kids were disappointed in the fact that the food in the Windjammer was not open 24hrs a day, which was a novelty for our teens last year on Grand Princess.
That's my two cents.
