We wanted to experience the largest ship on the waters. The shows and entertainment were top notch. Loved every minute. The main dining room and the staff were excellent. Food could not have been any better. I was very disappointed in the Royal Casino. The slots were so tight you don't have much chance to win anything. Also the room we stayed in was very noisy when water was a bit rough. The room was on 7th floor, 512. I don't recommend it unless you can sleep through anything. There was a loud boom on a regular interval followed by a fairly hard tremble. When water was calm, it was quit peaceful. I don't know how many rooms around us were affected by this. My husband and I really enjoyed the whole experience for the most part. The embarkation and disembarkation were fast. As long as you pay a bit extra they take your luggage from your hallway night before and you don't see it again until you reach your flight destination at luggage carousel. Download the passport app to your phone and fill out during breakfast. Then take your declaration paper and follow the "mobile passport" line and you are through customs and on your bus to the airport before you know it. We would gladly cruise on Harmony again. Just make sure room on different floor and stay away from casino.
The room was pretty small, but that did not bother us. The loud boom and vibration did. If the water was a little bit rough the noise happened on a regular interval. But when the water was calm, it was quiet and peaceful. On our trip, we got rest about 3 out of 7 nights. I do not know how many rooms around us were affected.
