Welcome Paul. My husband is a keen golfer and thoroughly recommends both courses at Orange County National, which he always plays. He also enjoys Southern Dunes and says it is a very pretty course, also look at Diamond Back past Southern Dunes, Grand Pines, and his favourites are at Mission Inn at Howey-in-the Hills where they have 2 courses.
If you want more info I can pick his brains! Check out OCN webpage as they do specials including lunch and a $25 voucher for the club shop, also look out for the booklets near the restaurants and at the outlets - they usually have offers for one course or another.
