I went 20 years ago and got to go back last fall, during Howl-o-Scream. I had a blast! Griffon and Apollo’s Chariot are awesome. If you love roller coasters, you’ll love BGE.
Since it was September, the weather was just right for spending two days at the park.
Recommend eating at the the Trappers Smokehouse. Extras can bring the cost up, but the food is great and will fill you up for most of the day.
