Small bachelorette party activity?

My friend is getting married (her first) at age 42. We are having a small bachelorette party at one of those wine and painting places. The owner said we could bring in food. My question is the class is three hours long. People can do whatever during the class (eat, mingle, drink) however, I don't want to have any food that requires someone to sit down and eat. Looking for different types of finger foods that do not need to be served warm. I am having the usual cheese and crackers with some fruit. Any other ideas? thanks
