Hi B.,
I live in Orange County and I know that some of the public schools have a summer program for kids in your situation. My daughter's former elementary school had the extended day program from about 7am to 6pm almost every day and it was really nice. It was run by several of the teachers (plus high school students and other employees), they provided snacks, activities, field trips, computer time, art, playground, movies, etc... She enjoyed it and it was familiar to her. Also, there are park and rec programs that do basically the same thing. I live in Apopka and there is one offered for the city of Apopka. A neighbor has been sending her son there for several years. The city you live in might have someting in that realm, too. Good luck!
