Oak trail may only be a 9 hold course but it is the better amintained than any corse in my area. I thinking walking is an important part of golf so I enjoy this course over the other Disney Courses where golf carts are required.
The course marshalls where very friendly and helpful. One even went back to the clubhouse to get me some balls from the driving range after I had lost all mine in the woods.
Very nice course, well maintained. It is the same terain as Magnolia. Only problem, at 65 years old, the walking was not my cup of tea.
I was 18 years old when I attempted Oak Trail, I went to Oak Trail because I didn't want to spend a lot of money and I didn't want to attempt 18 holes. It's the only 9-hole in WDW, so it's good for the younger crowd. I got a tee-time for 3:30 in the afternoon, due to the price. The price drops significantly starting after 10AM. The heat wasn't a problem, but you must remember to wear sunglasses or at least a cap or visor.
The only sour point for the day was when I sliced my newly purchased "fantasia mickey" golf ball on the first hole. After that though, I hit every drive fairly straight. It was a good day, it's definately the best 9-hole I've ever played!
The only problem I found was the "no-cart" rule. Their are no Electric Golf Carts to rent, it's a walking course. You can only rent a pull cart.
