Also, if you want to see for yourself whether you think Cedar Hill (can't speak for the current conditions, but can speak for the layout) is NT-level, you can watch these videos from last year's MCO and see for yourself.

Hole 1: Shorter than 2020, hole is located near the last gap in the trees (about 80' short of the 2020 placement)
Hole 2: Longer than 2020, hole is located further up the hill where the yellow basket is in the video (Inner Hole II's Pin).
Hole 3: Same as 2020
Hole 4: Same as 2020
Hole 5: Same as 2020
Hole 6: Shorter than 2020 based on the caddie book, but I can't think of what pin position they're using. Guess we'll wait and see.
Hole 7: Same as 2020 (best hole on the course, IMO)
Hole 8: Same as 2020
Hole 9: FPO is the same as 2020, MPO's basket is straight ahead near the edge of the woods and the parking lot instead of making that dogleg to the right to enter the downhill wooded section. (some guy threw a disc at the filming drone on this video)
Hole 10: Shorter than 2020, they are playing from the shorter alternate tee.
Hole 11: Same as 2020
Hole 12: MPO is same as 2020, FPO's basket is 100' shorter at the pin position in the middle of the fairway near the top of the hill.
Hole 13: Same as 2020
Hole 14: Same as 2020
Hole 15: Same as 2020
Hole 16: Same as 2020
Hole 17: Same as 2020 (most fun hole for noodle-arms like me, if you like downhill bombs)
Hole 18: Same as 2020 (spray and pray)
I've never been to Mill Ridge and had no involvement with the tournament, so I can't speak for that course. I've played Cedar Hill many times though, so I can answer most questions about it.
