Saw this place from the highway quite a few times and figured that it's location in Charlotte would mean that it is Busch League. I was pleasantly surprised that it is actually a pretty legit theme park.
It is owned by Cedar Fair, which is good news since I went to Cedar Point in Sandusky, OH and it is the best, some of that has rubbed off here because they have a good selection of quality coasters.
We went for Scarowinds (Halloween themed) and it was reasonably priced. Of course parking and any food or drink in the park are ridiculously priced.
The lines when we went were OK and vary between a few minutes for an old wooden coaster later at night and a long time for The Intimidator (worth the wait).
All in all a pleasant surprise and worth a trip if you can find a good deal.
