Age Restrictions

On Board Baby-Sitting
Costa offers group baby-sitting for children age 3 (out of diapers) and older. The babysitting schedules can be found in the Daily Program distributed onboard (private in-stateroom babysitting is not available). There will also be two 'Parents Night Out' during the cruise where parents have the opportunity to enjoy the evening worry free while their children will be entertained with special activities, including their own buffet or pizza party. Best of all these special nights are offered at no extra charge.

Costa's In Port Children's Program
Caribbean: Costa's In Port program offers children a variety of activities onboard to entertain them. Parents will receive information pertaining to scheduled activities at the beginning of the cruise. Ask about specially priced shore excursions for children 12 years and under.

Europe: Costa offers a comprehensive children's program throughout our Europe cruise season. The months of July and August are the most popular traveling times for families with children. Activities vary by ship and itinerary.

If you require prescription medications, bring an ample supply. Some prescription medications, might not be available onboard or ashore.

Kenny

The variety in their menu is limited. Have been on few cruises with Carnival and their selection of food is much better. Had a problem with the WiFi service on board the ship. Paid 32 Euros for a connection, but was unable to use the service. It appeared that most of my data allowance was used up when I switched on my laptop. I was told that the problem was probably due to my system set to automatically update itself.
