If you go to the top content slider at the top of our page, you'll see it scroll around to a summer camp list. That is one place to get started. There's also the YMCA but it is not inexpensive. (to me it's not ;)) They do offer scholarships there but they also have summer programs. There's a lot of wonderful camps this year depending on if you want art, horse themed, sports etc. :) Good luck and welcome to the area!
You should contact Family Ties Learning Care Center at 352-854-3998. The owner/directors, Ken and Karen Hagenhoff, are wonderful and offer a school aged summer program at both of their locations. (one off of West SR 40 near 60th ave/airport Rd and the other on Baseline rd.) They also have a full day care for 6 months and up with VPK and have after school program too. I have had all 3 of my older kids in different programs with them, and if I go back to work (which may not happen becaus I am really blessed to have the chance to be a stay at home mom!) I'll send my now 7 month old to them as well.
