I agree with the others here. While I enjoy the "latest and greatest" experience of the new ships, if you enjoy sailing on Carnival, then since the Holiday has left the fleet, there is not a ship that is so small that it can't offer the same amenities as the larger ships. The Fantasy class ships were HUGE when they first came onto the seen. The have most of the same offerings except for the the special spa rooms and the steakhouse specialty dinning ... so I would not dismiss the smaller ships... if the price and itinerary is right, go for it. Something else to be considered, the larger ships can not dock in some ports due to their size, so the mega ships tend to have the same itinerary ....
As macmom said... if you have never been on a smaller ship, how do you know you prefer the larger ones?
