Old Memorial is a very exclusive, expensive, well conditioned club with a better than average golf course, and that's all.
World Woods has two world class golf courses that are in the best condition they have ever been. You don't have to trouble anyone for access, and it costs less than half of what Old Memorial will extricate from you. I see no reason to go anywhere else.
I like the TPC Course at Tampa. It is not affiliated with Cheval, which is an overpriced real estate development with mediocre golf next door.
Palma Ceia is good but not great. It is tightly crammed into a small amount of acreage and to me has a crowded feel to it. If your friend is itching to play an old private club, go for Temple Terrace instead
Lake Jovita is pretty well regarded, with some of the more interesting greens and contours in the area
Sugarloaf Mountain is no where near Lake Wales, t is around Clermont. I am not sure if they have 18 holes open yet.
For the budget minded golfer, try Bloomingdale or for a quirky day, try Scotland Yards.
The sleeper is Brooksville CC
Good luck,
