I enjoy them all, but interestingly I like Osprey and LBV both the best. As someone else said, Osprey is a beautiful course. It has changing elevations, dense forests, gourgeous views and no adjacent fairways to where every hole is truly on its own and you'll hardly ever see another golfer ... an excellent golfing experience. LBV is a different feeling, what with OKW and SSR bordering it, but I find it fun and have had fun exchanges with folks on their balconies at OKW. Maybe I'm biased, too, as OKW is one of our home resorts and perhaps my favorite, so I enjoy playing golf meandering through one of my favorite places to be.
This isn't meant to diminish either Magnolia or Palm, just that I personally enjoy these other two better. They're all fun, though. One additional course that hasn't been mentioned yet is Oak Trails ... a nine hole walking only course. Fun to do, too!
