Intimidator and Cobra, and that's all you need to know. Go.
Intimidator replaced my favorite coaster of all time (Millennium Force at Cedar Pointe) and the adrenaline rush afterward made me feel as though I accomplished something big. I have no idea how no one has fallen out riding this - the seating design is revolutionary and freeing and allows completely uninhibited body movement from the waste up. It is the only coaster my husband felt terrified of while riding and he begged to skip this one a second time around. I, for one, felt very secure for some reason and loved the height and speed. It was a serious thrill.
A first for me was the backwards coaster, Cobra. I'd never experienced this kind of design and it was such a blast. The first drop going forward is amazing, and then you reach the midway point and reverse going backward while going upside down multiple times. It was scary, exciting, and unique.
I really liked how the park was designed - no space was wasted. You do not have to walk a quarter mile between fun things to do. The park is huge and hosts a surprising amount of roller coasters, but we did not feel exhausted walking the park itself all day. It was incredibly easy to navigate. Additionally, there were so many cool kid's exhibits and rides that were a big step up from most amusement parks I'm accustomed to.
My only real gripe is with some of the workers. We spoke with a handful that were just really, really weird. Not creepy... Just a bit off. There was a lot of over sharing involved. The guy that did our caricature portrait also flat out sucked! The drawing was AWFUL! It was disappointed and not creative at all. Kind of middle school grade.
This is a great park and absolutely a must do if you are in the Charlotte area. Very comparable to Cedar Pointe and more affordable.
