Planning a JOINT Bachelor/ette Party - I need your help!!! Got any great ideas?

I am the MOH and have been asked to put together a joint bachelor/ette party here in Sacramento, CA. As you know, Sac doesn't have the night life like places like Las Vegas and we need to have it here in town. I have been racking my brain what kind of activities I can plan to have the off the hook Joint Bachelor/ette Party ever. The party consists of only 5-7 people total - so whatever I come up with needs to be fun and fit for a small group of people. I can only come up with ideas like... bowling, wine-tasting, golf, and stuff like that, but these aren't the greatest of items. I wish Sac had a Dave & Busters - I heard this is a fun place to hold a joint party. Does anyone know either from personal experience or word of mouth any ideas on what I can do to plan this event? I seriously need some help!!! Mucho Gracious!
