We decided to vacation on the Harmony of the Seas, due to the size of ship and we wanted to try R/C, we had previously sailed with other cruise lines (5 cruises). However, we were extremely disappointed with the regular dining and upgraded restaurants, the food was dry and tasteless, upgraded restaurants were overpriced for average food that wasn't anything special. The drinks were overpriced and very weak (and we aren't even big drinkers). Communication was poor, there was a problem with some of the show productions and shows were cancelled for the first 3 or 4 days and no effort was made to accommodate for the inconvenience. The service (staff) on the ship was far below service compared to other cruise lines we have traveled with before. The ship was beautiful, but the onboard experience was not good, we didn't feel like the staff was interested in pleasing the passengers, R/C should stop trying to build oversized ships and focus on the onboard experience.
