The embarkment was not smooth because their check in process on their handheld device was not working properly. I couldn't carry on my luggage as I normally would at other ports because they said it wouldn't fit through their machine so I had to open it up and dig through it for my wine bottle to carry that on separate per the policy then later that evening I found my luggage on the side of the elevators for all to grab because apparently the name tag fell off and Carnival decided it was ok to place the luggage on the side of the elevators around the corner from the front desk. Our room was on the 8th floor in the back (8426), worse location I have ever been at on a ship. It was on the corner next to some utility room and either you hear loud guest coming from the elevators or you hear creaking movement in the utility room from the ship rocking all night long. Never quiet. Some parts of the ship was hot and some were cold. It was overcrowded and people reserved chairs on the deck or they moved lounge chairs to place elsewhere. The Serenity deck was only free while in port because again pods/chairs were always saved, even while people went to dinner. The ship was clearly crowded and people were rude and acted ridiculous when there was a mechanical issue and we couldn't stop at our last port (Amber Cove). That did baffle me that there was a mechanical issue already on what was supposed to be a new ship. Overall, the ship had one of the best entertainment shows I have ever seen on Carnival and plenty to do for all ages. You could not be bored on this ship. We mainly ate at the specialty dining rooms, however, service was excellent everywhere we went. I wish Carnival would change out their dining room menu for those that cruise often though. It does get redundant. The casino manager and her companions were excellent, the wait staff, especially YASA was amazing. We also did "behind the fun" tour and it was superb. Personally I like smaller ships with less people but overall the ship was something different than the rest.
