Most cruise lines have a children’s program, divided by age group. Games and activities are age appropriate. Children can participate as much as their parents want them to. These generally include games, physical activity like using a playground or pool, and arts and crafts. Sometimes there are dances and social activities for the teen group.
Some activities involve more physical activity than others. There are ships that have pools, water parks, ice skating rinks, climbing walls and areas for golf (lessons or miniature golf). Skeet shooting off the deck is another option.
Arts and crafts are usually available for all ages. Some ships even have art fairs!
The on board theatre will run movies, both general and adult oriented. Board games, bingo and keno are examples of more sedentary activities to engage in.
Some cruise lines feature lessons, all sorts. You can learn a foreign language, how to cook foreign fare or gourmet meals, how to play golf, poker or dance.
Spas provide massages, hair care, manicures and pedicures and other special types of treatments for the body. Think how good that would feel after dancing in the disco all night!
If you have a special interest or avocation there may be a cruise with it in mind. The sounds of the blues, or a family oriented cruise, or special cruises for singles.
