Is there a dress code for Grad Nite?

Yes. We don't require black tie and formals, but you should definitely dress comfortably. Make sure to check the weather too! A light jacket may be a good idea. Additionally, all schools must adhere to their school's dress code policies and must meet, at minimum, Six Flags St. Louis standard park dress code.

What if I don’t like roller coasters? Are there other things to do?

There is no shortage of fun during Grad-Nite! We have a DJ-hosted dance areas plus interactive games and activities around the park to keep you busy.
