According to the Carnival brochure about Camp Carnival, All children are supervised by counselors who are college educated in a related field, have professional child care experience or both. You do not have to worry, your children will be just fine. These counselors are highly trained, most are in their 20's (young at heart) and love working with the children. My daughter has always gone to the programs offered on the ships and loves every minute of it. If you are concerned, the best thing to do is GO on the first night to the kids program, check the childrens facilities out and meet the counselors. I am sure you will be impressed with what you see and feel confortable leaving your children with them.
I don't remember what your childrens ages are but here are some of the activites listed in the brochure:
TODDLERS: (2-5) Finger painting, Outdoor fun, Movie night, Pizza pig out, Candy Bingo, Story Time, Cookie Decorating, Face Painting, Breakfast with your Youth Staff, Mini Farewell Party, Circle games, T-Shirt painting, slumber party, Play-Doh time, Candy Art, Sand Art and many more activities.
JUINORS: (6-8) Pirate Hunt, Talent Show, Pizza Pig-out, Olympics, Outdoor Fun and Games, Indoor Beach Party, Play Station 2, Game Boy Fun,
Coketail Party, Ice Cream eating Contest, and many more activities.
INTERMEDIATE (9-11) Come have breakfast, Swimmin Under the Stars, Karaoke, Show Time, Meet the Entertainment backstage, Jewelry Making, Board Games, Scavenger Hunts, Talent Show, Ping Pong, and many more activities.
There are many more activities for the older kids. As you can see you will not just be handing your children over for someone to "watch" they will be active throughout the entire time they are at the camp. Do not be surprised if they decide they want to spend all their time at Camp Carnival instead of with you.
