Hey there - Take a look at http://baseballcamps.com/campdetail.cfm?Camp=1903 This one starts in July, lasts for 3 weeks - This camp is 13-18 yr olds taking place in Lakeland, Fl

This one is much shorter - http://baseballcamps.com/campdetail.cfm?Camp=2565 Its a Nike camp for ages 10-18 in Lakeland, FL

Lakeland is about an hour away from Orlando

This is a great resource that shows numerous other camps in the state of Florida.

Hope this helps out, best of luck!
