While the service crew were outstanding, and tried their hardest to make the cruise pleasant, the truth of it is that this is a Sea Bus. It is overcrowded (which makes good service very difficult), the ports of call are boring, with very little to see or do (a lot of passengers stayed on the boat and didn't even bother to get off), and far too much time is spent at sea (about half the days are sea days). With 6 of the 14 days at sea, and some shortened (1/2 day) ports of call, you would think Royal Caribbean would step up the entertainment, but the best they could do was multiple trivia games all day long And good luck finding a place to sun around the pool! The hot tubs were always taken over by legions of teens; in fact, children could be found running unsupervised all over the ship. Unless you want to drink heavily, sun yourself daily, and let your kids run amok (or experience others who do), I suggest you find another cruise.
Malaga was a lovely port for walking around. The ancient Moor castles and the Picasso museum were worth seeing (and within walking distance of the ship port).
The train is right at the port, so we were able to go to both Cannes and Monaco. We enjoyed seeing both cities.
Corsica is a lovely little island, with a quaint town and Napoleon's home / birthplace. The beaches were small and not exceptional.
Sardinia was not very impressive. Big city and the "premier beach" was crowded (on a Monday!).
Mallorca was lovely to walk around, with plenty to see and do, and the food was fantastic.
Boring! You know there is not much to a city when the local sightseeing bus feels compelled to take you by the shipyard and tell you how much the shipbuilding has meant to the local economy.
