Figured I might as well post how the trip went, in case anyone follows in our footsteps.
We played -
Camp Catalpa - Richmond, KY - I rate it as a 3. Nice fun, short course in a pretty park. One set of 9 tees with two baskets on each.
Richmond Hill - Asheville, NC - I rate it as a 4. It was a misty morning and the course was pretty wet, but we had a good time. I'd have rated it even higher, but too many holes across the ravine felt similar. A few tee boxes were pretty sketchy too. Very fun and fair course for intermediate players.
Sandhill NT - Asheville, NC - I rate it as a 3. Very nice, level tee boxes. Lots of forehand friendly holes and several ace runs towards the end. A few holes are too close to soccer fields and roads though. Good variety of holes.
Catawba Meadows - Morganton, NC - I rate as a 3.5. Very nice, new tee boxes. This course was our halfway stop on the drive from Asheville to Charlotte. After playing wooded courses the last two days, this open, park course was fun to throw bombs on.
Charlotte Area Courses -
Bradley Center - I rate as 3. Signage needs to be repaired, but this was another fun wooded course. Nice use of elevation and a fun finishing hole.
Robert L. Smith - I rate as 4.5. Very nice course in a big park. Lots of memorable holes - 3, 9, 12, 17, 18 and nice variety. I loved this course!
Goat Island - I won't rate this one as I'd been having a bit too much fun with Charlotte Beer Week, and my memory of the course isn't the best! The park was also really busy with walkers, picnickers, etc. on a beautiful sunny day, and that interrupted the flow on a few holes. This is also the only course I lost any discs on as I had two wind up in the river.
Hornet's Nest - I rate as 3.5. We played this the day after the tournament, so there was pretty good signage up that helped us with navigation. Nice enough wooded course, but I really missed the elevation changes most of the other courses offered. If you don't want to hike up and down hills, though, that might be a plus.
Rolling Pines - Wilkesboro, NC - I rate 4.5. Nice new course with top notch amenities and an excellent mix of open and wooded holes. It's a toss-up between this and RL Smith for my favorite course of the trip. Just a great place to play a round.
Warrior's Path - Kingsport, TN - I rate a 3.5. We didn't have time for the full 27 holes, but the 19 we played were mostly tight, wooded holes. Lots of mid-range tee shots as the course is mostly fairly short. Picked up several birdies, so this was a good way to end the trip.
And those are the 10 courses we played in four days. I was also super impressed with the local beers. Green Man, Wicked Weed, Red Clay Ciders, Wedge, etc. Many really excellent beers were consumed!
Thanks for all the suggestions in this thread. I wish we'd had a few more days!
