Each year, we take over Fun ’n’ Stuff in Macedonia Ohio for a night of go-karts, free play arcade games, laser tag, mini golf, and more!

Alcoholic drinks will be available until 2 am at the bar downstairs in the additional seating area, and the snack bar will be open all night/day!

No need to pre-register. You can pay by cash or credit at the door. We’ll handle admissions starting at 10 pm, so when the doors open, you’ll be ready to go in. We have the attractions from 11 pm-6 am.
