Dan, when people ask for recommendations around Orlando (like you did), the responses on the board make it pretty clear that members of this site don't like golf around Orlando. I assume the purpose of your trip is to take instruction from Bender. If it were just to play golf you probably wouldn't have booked lessons.
In no particular order, within 25-30 min from where you'll be:
Timacuan (I think Bender still teaches there)
Deltona Club - easy to get to, fun to play, just N of Orlando
Victoria Hills - as good as any course, private or daily-fee, within 45 min of downtown
Eagle Dunes - less flash, more substance than nearby Red Tail
Have not seen it, but Sobieski's suggestion of Deland is worth considering.
If you expand the drive a bit to 45-60 min:
Mission Inn (El Campeon)
Sugarloaf Mountain
Bella Colina
LPGA International (Art Hills course)
GC at Cypress Head in Port Orange
An hour from you on the other side of Orlando you can hit Champions Gate (2 courses), Orange County National (2 courses), or Reunion (3 courses). But since you are nowhere near the tourist's side of O-town, why not keep your life sane and avoid those like the plague?
Mike Dasher posts on this board and is the designer of Eagle Dunes. He also was the lead field guy (I'm pretty sure) on the project when Cypress Head and the LPGA were built as he worked for Art Hills for a long time.
Finally, you will be just around the corner from Mayfair. Once a PGA Tour stop, it is possibly worth a play only to tell your friends about the million-dollar lawsuit. Thought to be designed by Donald Ross, the present owner is claiming it wasn't. Do a search on this site for Mayfair and you might find the story.
Have fun. Hope we have some good weather for ya'.
