NCMP is a must. I was there about a month ago and even though it was not prepped, it was still a great time and decent conditions. (they prep on weekends) very fun safe layout, good jumps, fun little sx track (like a large scale nemx or ram jam) even the 'intermediate' track is fun to play on.
went to center road once, good time as well. east bend and a place called thunder valley (i think) both have night practices i believe. not sure where east bend is compared to charlotte but i think thunder valley was about a half hour, you could prob hit 2 in one day if you do it right!
have fun, i love it down there.
im leaving in a couple weeks for a trip to australia, singapore, and then hong kong!! my dirt bikes going to miss me for a little while!!!
