Try the Adult Activity Center or Meyer Civic Center. The Civic Center can hold 250?? But the Activity Center is a do-it-yourself setup with a basic kitchen. You cannot put up decorations on the walls but they provide the tables and chairs for up to 100 (??) seats, and have room if you don't set up all the tables for a dance area. This is what I have booked for April for $150 for 8 hours (plus $15 for each additional hour).
