My Wife and I took our first cruise on Enchantment of the Seas. It was an 8 night Western Caribbean and Coco Cay sailing and we were very pleased with the entire experience.
We talked to a lot of the crew members on the ship, and one of the things that frequently came up is how much some of them enjoyed being on the small ships more than the big ships when it came to passenger interaction. They felt like they got to know the passengers on the cruise a lot better, and a lot of the time it made for a better time at the organized events since they would see the same people over and over.
I think it makes a lot of sense. I know that on some of the bigger ships I'd maybe see the same event organizer at 1 or 2 events, but on Enchantment we saw the same crew members most of the time and got to know each other by name.
Also, like Jenna said in her article on the blog yesterday as well, if you are looking to relax with a book by the pool, the smaller ships are probably a great way to go.
