The cruise
1. Do not pay a lot of money for a cabin on the top decks. Lower decks are OK and they are quiet.
2. Do not buy trips from the Carnival. Economize and buy them locally.
3. You do not need to bring water on board as there is access to water, juices, tea and coffee 24 hours a day. If you love fizzy drinks, bring them because they are not free.
4. Dine at Lido deck. The choice of food is great and you can try what you want.
5. Enjoy the ports, visit new places.
