We aren't having a bridal party, so we aren't planning a rehearsal dinner; however, everyone is coming from out of town, and a lot of our guests are people we haven't seen in forever. I would like to gather everyone together the night before, but we aren't sure what to do. We want something where people can freely mingle, which means a sit down dinner is probably out. Our guest list is 40, and I imagine somewhere around 20 will come out the night before. Any ideas appreciated!
