I just got back from a cruise with 56 people on the Harmony and it was awesome.
We planned this trip for 889 days, read a ton of reviews, and tried to plan everything we could to maximize our time. The trip was great and we weren't able to do everything on the ship.
Everybody in our group found their favorite things to do, places to chills, activities to win and bars to grab a drink at.
We only got off the boat for an hour to shop
We met up with most of our group at a sushi place and just hung out the night before the cruise.
Played a lot of beach volleyball while my wife laid and her friends laid out by the water.
