Pros:
The Wilmont is a great course to work on distance, with some really long holes. Your driver game better improve if you've been playing this course after a while. Hole 14 seems taylor made for new RHBH players with drivers that are too fast for their arms (i.e. noob hyzers with overstable distance drivers in max weight/premium plastic). Wind is fairly common so the Wilmont is a great course for working with the wind, so you'll get a chance to have some head and tailwinds.
Holes 14,15,and 16 are great for working in a little elevation. Make sure you steer clear from the Wetlands, as your disc may be irrecoverable. When I came to play there was a group finishing, and a foursome ahead of us, so this course may not be in frequent use. This course is an excellent example of how disc golf is used to bring more use out of an otherwise under-utilized part of the park.
My favorite holes are:
1-3 in the woods, as you can set up/luck out with some shots that miraculously make it through trees.
Hole 8 has a nice finish to it with a technical upshot/putt with water hazards behind it.
Hole 14-16 are great fun and the hill of the amphitheater can be seen through the course, like some foreboding castle. Make sure your discs stay away from the wetlands.
Cons:
The negative of the Wilmont course are:
Tall grass - If you lose sight of your disc and it tombstones, you're in for a long search.
Bring a map or someone who's played there before, or you may get lost/confused as to were the holes are.
I wish the tee boxes were at least asphalted but oh well, it'd be tough to get that kind of equipment around here, I guess.
Other Thoughts:
I've heard so much about this course from my buddy, who's been playing since 2001, about how long this course was. I don't take the par 3 6-800 foot holes as a negative, but rather as a challenge to work on my technique so I can increase my distance game. To me, it beats throwing in a field for distance practice, because at least you're playing a round of golf. I played MacGregor Park, TC Jester, and the Powell course, so it's nice to be able to grip and rip without fear of hitting some park users (well, maybe hole 18 if there's a big party). I like throwing a couple extra discs down hole #16 just to see them float forever, and I love throwing my 7speed/7 glide disc at hole 15 just to see it get carried in a tail wind. If you don't like the distance of this course, you can always play the Powell, or even the Woody DGC just a few miles east. Heck, there's a great bike shop/ disc golf store close to Woody as well. Warm up your arm and shoulders, this course is a workout!
