Do not attend the safety drill the first day
Many veteran cruisers consider the safety drill as boring and unnecessary as the safety demonstration on an airplane. However, it is not only advisable to attend because it helps you know how to act in an emergency, especially if it is your first cruise, but it is MANDATORY.
If you do not attend this activity, which is normally scheduled for the first day of travel before the ship leaves, you could be expelled from the boat.
Bring camouflage clothing to the Caribbean
You can carry this type of clothing in your suitcase, or even use it on the boat. However, it is strictly forbidden to use it in several ports where the boat stops on a Caribbean cruise. In Jamaica, Barbados, Granada and St. Kitts, which are destinations visited by cruise ships, wearing camouflage clothing is illegal. It is a security measure, to differentiate clothing from military personnel.
