Nita, Camp Carnival's program is set up that if the child is 9 yrs or older they sign themselves in and out. Under the age of 9 the parent signs them in and out. I would suggest that you take your son to the first night gathering of Camp Carnival so you and he can meet the counselers and the other children in his group, and get the Camp Carnival Schedule for his age group. He will be in the Intermediate group which is 9-11 year olds. Some of the activities include:
Swimming under the Stars, T-Shirt painting, Karoke, Indoor Beach Party, Meet the Entertainment Backstage, Jewelry Making, Scanvenger Hunts, Talent Show, Outdoor fun..and so much more.
So you will feel comfortable with him signing in and out himself, just let him know where you will be most times, or you can invest in a set of 2-way radios. This way when he signs himself out he can find you.
He will have a great time!! Relax you will have a great time also.
