The staff was great. I went on a Saturday around 1 pm there was a lot of people but the lines weren’t very long the max you’d wait probably 5 min. The rides were great an the park was beautiful I loved it will definitely go again. The food was pricey but that was expected.

We went during their Friday night carnival nights - I’m sure during their regular hours it’s fabulous but in the evening special event a lot of rides were shut down, about 1/3 of the midway games were running and the plant gardens weren’t quite lit enough to feel safe to explore. I’d love to go back during their normal hours sometime.
