Depending on where you stay in Orlando, there are a few.
Shoot Straight has facilities in Apopka and Fern Park.
East Orange is on Goldenrod, near HWY 50, a few miles west of UCF.
There's an indoor range near Oak Ridge High School; I don't know if they have rentals or instructors. (East Orange has both.)
There's a place near I-Drive that has NFA submachinegun rentals, if you ever wanted to try that, but I can't remember the name.
