I've played all the courses once. I'd have to say that Fantasia Gardens wins for atmosphere.
Sheer whimsical theming goes to Winter/Summer land.
I liked the hard course at WinterSummerland... but maybe that is just me. The course is set up just like a real golf course, but you have to putt your ball, a very long way, across the fairways, avoiding traps towards the "green." Think of a typical golf course layout and miniaturize it. This is what you get. It was hard and at times frustrating. But since I am a bit competitive at golf... it gives me more reason to go back and see how it can be conquered better. For those who play Golf.... the real game.... it really tests your ability to read long distance puts over a rolling surface. Getting Par on most of these holes is an extreme challenge. Actually just getting your ball to stop on the "green" is challenging. I'd like to see the PGA & LPGA players take a spin on this course when they come to town for their annual late-year stop.
Anyways... I will definitely have to play again in January when we make our next trek down.
