Embarkation we got to the port at around 2pm and took less than 40 minutes to get on board. The staff were extremely helpful. We were able to go straight to our cabin and our bags arrived in the afternoon. This was one of the only days that the famous slide was available (because it was only open for limited hours and shut during high winds - which we had plenty of) so we were glad our son could use it that day.
Music is everywhere on this ship. The fun ship ethos means that if you like peace and quiet from time to time there is nowhere to go. We noticed that at 9am the music volume on the public system is turned up so they can be sure you are having fun. The outside lido deck area is very noisy.
Fitness the gym is well equipped and the instructors are knowledgeable. However the pools are all far too small to have a proper swim. The hot tubs were luke warm at best but were almost always busy with large groups.
