Interesting question with some interesting spelling. If you've never ridden a hypercoaster or a flying dutchman, I'd say SFA for sure. If you've never ridden a B&M inverted or America's only dual racing coasters, try Hershey. Hershey definitely gets a lot more crowded, especially on weekends because it's older and more established. In my last two experiences, The Comet, Great Bear, and Trailblazer had the worst waits out of the coasters there. At SFA, expect long lines for Two Face and Batwing. S:ROS is hit or miss on lines. As for flatrides, both Hershey & SFA have their share of older flatrides, but both have new ones as well such as the Chance Chaos. Can you go to both parks somehow? It would make your life a lot easier.
