Okay so first off I am not a snob or picky AT ALL but if you have not booked yet, please let me convince you not to. I am a five time cruiser, 19 years old, and this was by far my worst experience with cruising. So for 18 to 21 year olds, there was not much to do but I had a big group so I still definitely had fun.
First off the only thing open past 9 or 10 o'clock was the nightclub. I remember they kicked us out of the hot tub at 9. The buffet food was average but the problem was only open til about six o'clock then they shut down 75% of it so when everybody got done with the show everybody had to wait and they ran out of food, very unprepared. At about ten at night, they closed the buffet down completely so if you wanted room service after that there was a service charge and they only had salads and wraps. If you are going on this cruise and planning on going to the night club take half a pizza and put it in your room.
The DJ, in the nightclub would play the same music every night. I remember one night it was Request Night and he said "requests are over I play my music now." On past cruises they had comedy acts and great shows. On MSC, they had the same AWEFUL AWEFUL show every night with no comedy clubs at all. One night they had a karaoke in one of the smaller lounges, the black and white lounge, and it was the only thing to do on the ship so there were was literally about 800 people in a room that probably was meant for 250 people.
Cabin is what is expected on the cruise small and clean.
Rented jet skis on beach, NEGOTIATE/HAGGLE. We got over 1/2 off asking price
Team vs Team, traveling the city. Fun to explore, I believe it was called an amazing race or something.
