As a keen golfer from the UK, I'd have no hesitation in recommending the Disney courses - particularly LBV and Eagle Pines. Outside of the World, the best course we've found so far is Diamondback. It's a bit of a drive but the course is absolutely beautiful (a waterfall on the back three!), a hell of a challenge and cheap as chips (a UK phrase, sorry!). Because it's a bit of a trek from WDW the prices are much more favourable and the deals they tend to offer are superb.
We normally play Highlands Reserve as our warm up round - it's relatively open and straight forward, but the people are friendly, the deals are good and it's gives everyone a chance to get their game in shape before tougher tests.
Other fun courses we've played are Southern Dunes (which seems to have more sand than the West Coast of Florida!) and MetroWest, which is another solid Floridian course.
I haven't played Falcon's Fire but I have heard it's a little overpriced for the quality of the course. Likewise Champions Gate. Orange National has two courses and gets great reviews but when we turned up to have a look and book a tee time the staff were pretty snooty with us so we didn't go back.
But please do try to get down to Diamondback, it's a hidden gem of a course.
Enjoy your golf, you lucky things!
