After reading lots of reviews we decided to buy, it was worth it. Harmony is a massive, impressive ship with everything you would like to have on a cruise. Everything for everybody, we were a group of 6 (3 adults and 3 children) on two staterooms, but everyone had fun. Children has lots of activities, specially designed Adventure Ocean is by far the best kids activity center on a ship, besides the ship has lots of pools for small, medium and big kids, great slides and even a surf area. For us the adults I enjoyed the giant 700 meters track on deck 5 for running or walking, there is also a decent gym with a big spa. The shows are very good, specially Grease and Columbus on the Royal Theatre which by the way is awesome. The aqua theater hosts another great show called The Fine Line which is amazing. There are also two more shows on ice, ISkate and 1887, another great thing is that during the day the allow everybody to skate freely. The ships has lots of shops, restaurants (20) and bars. I recommend this ship 100%
