Im an 18 year old that has played the Disney courses ( all of them ) MULTIPLE times. Though Magnolia and Palm are the PGA Tour preferred Disney courses, between those 2 I would probably choose Palm, just because that was the first course i've ever shot even par on.
Though, if you travel about 10 minutes into Disney ( away from Magic Kingdom & those places, ) A golf course called Osprey Ridge is located there. I absolutely LOVE that course! In my opinion, it is a bit more challenging from the tips, although its only around 7,100 yards, it has many obstacles throughout the course. I recommend you guys check that out next time you go to Disney!
