In the evenings you could try your luck in the casino, watch the latest films, enjoy Broadway style entertainment, dance at the discotheque or relax over a drink at the bar. Every Cruise ship has an equipped medical clinic with a full-time doctor and staff who can cope with emergencies. On a typical one-week cruise there are usually one or two formal evenings. The rest of the time is casual on-board. For such occasions it is advisable to carry a dark suit for men and cocktail dresses for the ladies.
Tuxedos are available on rent on-board the ship.
Most ships usually get into port early in the morning and don't leave until that night or early the next morning so that leaves plenty of time for sightseeing, shopping and relaxation. You have the choice to return to the ship for all your meals. You can never be too early to book a cruise. Most Cruise lines offer early booking discounts. Cancellation policies vary with each Cruise liner.
