Can you find her just a general day camp where there isn't a focus on a specific activity? My son (who will turn 6 in May) went to a general camp last summer and loved it. They did coloring, other crafts, played on the playground, read books, played board games, sang songs, etc. He really loved it and is planning to go back this summer three mornings each week.
Does she have a friend that she can sign up with? That might help, too, since she won't feel alone.
I really think a general camp is best for her. It doesn't sound like there's a specialty camp that she's ready for this summer. I just read your SWH - I can't imagine there isn't a general camp out there. Our city offers tons. Can you ask other parents at her school, especially those with older siblings, what they have done?
Is there a YMCA or a Boys & Girls Club?
