Holland America or Princess? How do they compare to Carnival?

Cabins are not that much smaller with Princess than with any other cruise lines. In fact, I would bet you would not notice them smaller at all. Princess Buffet does not suck. They have a wide range of food. The only things is the buffet does get crowded, so that is why I almost always eat in the dinning room. In the MDR, I find the food excellent. Princess also has far less old people then Holland America. Holland America is about 85% people over the age of 60. I have been sailing with Princess for years now and think they are top notch. BTW, Princess decor is much more classier then Carnival with a lot less gaudy color schemes.
