We have been Disney cruisers but based on others reviews thought we would try RC since our kids are getting older. The Harmony of the Seas is huge and jammed with people. For as much experience as RC has I would have thought they would be better at handling the crowds. Expected lines one some of the extreme activities but not at every meal. Windjammer would offer special entrees like stir fry but only have 2-3 people cooking on a ship with 6000+ passengers. Staff seems unhappy and almost annoyed by passengers. Drink stations are scarce unless you are looking for a bar and many of the drink stations are closed most of the time. Entertainment was good and water show is pretty amazing. The movies on board were all old so no real draw. The kids clubs are very limited and our kids hated them. They were required to do whatever the counselor on duty chose as a large group activity. Teen room was okay and seemed to have more options as they would occasionally close ping pong or basketball courts for teen only time. St Kitts was a great port and I highly recommend the rainforest tour as it is beautiful and there is some nice snorkeling right off the beach. The actual port in St Kitts is not very nice as they are new to the tourism world. St Thomas has beautiful white sand beaches and the shopping can be fun. Nassau is okay but the port time did not allow for much exploring. This is the first cruise we have ever been on that we didn't book another.
