Will be sailing on the Star in a few weeks. While I've never been on her, I was on the Pride of Aloha, now the Sky, which has a pax load 300 people fewer and is part of the smaller "Sun" class.
The small ships have a character and intimacy you just don't get with the behemoths. Don't get me wrong, I do enjoy the Breakaway Plus class and all the amenities. They're impressive. But the babies of the fleet are also comfortable. You can't, however, do a direct comparison between the two. They're designed for completely different markets and completely different customers.
