This is an exceptional vessel and that justifies the higher price. The ship is new and well laid out. It was easy for us to find our way around. The crowd was older (mid 50's and up) with few children.
The food in the dining room was very good with well prepared dishes and excellent service. We had the flexible dining option and were encouraged to make reservations. However, it seemed that whenever we called the only times available were before 6:00 or after 8:30. We finally gave up on that and found if you got to the dining room before 6:30 there was no problem getting a table.
Breakfast and lunch buffets were better then average. However two of the three dinner buffets we ate at were poor. The exception was the evening that featured a steak night with cooked to order beef and lamb. That offering was exceptional.
Entertainment was a cut above the ordinary with several excellent performers. The big shows were pretty much the usual fare which after a while becomes redundant.
The best ports were Bonaire, St. Lucia, and Barbados. Bonaire had exceptional snorkeling, Barbados beaches and St. Lucia variety. If you are into shopping, St Maarten is the best but expect big crowds as there are were 6 cruise ships docked during our stay.
We stopped at St Croix which was a quite alternative to the madhouse of St Thomas. The island is not much developed for tourism so your best option is to take a boat ride to Buck Island which has good snorkeling.
Overall, it was a great trip on a beautiful ship. If you have two weeks to spend I highly recommend this itinerary on the Eclipse.
