It is a shame these posts for Orlando course recommendations are tacked on to this old thread. I miss Matt, but I seldom post here anyway. This was a bad, bad thread.
If the question is Red Tail, Black Bear, or Eagle Dunes? My answer is definitely Eagle Dunes, designed by some time poster Mike Dasher. Others will disagree, but I think the community here will appreciate it.
Walkabout is good, so I'll second that mention.
Surprisingly, I have never played Rolling Hills. (There are only five area courses I have not played, all by choice.) I've heard it is okay. The site is awfully hilly, so there is potential. Also never played Deland, which Doug Sobieski has recommended since he played on the golf team at Stetson.
Mayfair isn't very good, but I did recommend it recently to the Mike Bender Academy guys because it is nearby.
Some in the Seminole County area to play: Legacy Club at Alaqua Lakes, Timacuan, Twin Rivers (near where I live)
Avoid: Magnolia Plantation
One mentioned Errol Estate. I'm a big fan. If the conditions are decent, the golf is very enjoyable. Not too close to Sanford though...maybe 25-30 minutes. Worth seeing near that is Rock Springs Ridge.
Have fun.
