Based on what I saw on Sunday paired with pictures shared on here, I'm optimistic in the improvement in food choices. The prices are right in line with what sporting events, concerts, and most parks charge so no complaint from me in the price.
As far as park improvements for 2015/16, I'd like to see them get back to some kind of consistent theming. I don't expect Disney or Universal level, but there is so much different character across the Carolinas, and the park has a unique name, I'd like to see them get it back in line with the existing themed areas. For example, when I go to County Fair section of the park, it should have some kind of feel like I am at one of the county fairs that used to be held around NC/SC (ok, maybe without real carnies

) Rides, food, and atmosphere should have tie-in to the theme. Carolina Boardwalk should remind me of the years that I lived on the coast of NC. Thrill Zone should be renamed.
Some focus and consistency on the theming would really add some southern character to the park.
I also wholeheartedly agree with the previous Ferris Wheel comments. I still can't believe we don't have one.
EDIT: It would also be awesome to see the parking lot fixed. It makes no sense on how to enter and exit the parking lot and someone is going to get run over one of these days based on what I saw this past Sunday.
