First let me say that if you are going to cruise, your maiden voyage should be on a cruise line of Celebrity's caliber. The Equinox was a beautiful ship and was run like a fine hotel. We docked in several ports with Carnival and RCCL ships and the contrast was striking. Those vessels looked old and poorly maintained compared to the Equinox.
The sailing was smooth and the weather was perfect, even counting the few overcast days that lent an appropriately moody tropical atmosphere. The hotel service exceeded my expectations. The service was swift and unobtrusive. But if you are sailing mainly for the food, it may not live up to expectations. The main dining room and specialty dining were good but not spectacular. After a while, there is a sameness no matter how it is presented. The buffet was a frightening experience where the worst behaviors of the passengers emerged. The high school cafeteria comes to mind.
The shore excursions centered heavily on jewelry shopping. This was appealing to many. I was happy to just wander around and take in the sights. I wasn't really excited about bus tours or playing with sea life, but those tours were plentiful. Many passengers raved about them.
Extremely quiet cabin; there was virtually no noise either above or below and rare sounds from hallway. It was comparable to a 4-5 star hotel. Spacious closets, bathroom, and balcony. Highly recommend.
