We are having our rehearsal dinner at a location where all they provide is the location, tables, and chairs. Our guest list is at about 40 people. We are stumped on what to do for music. We found a reaonsably priced DJ but we aren't sure if people are going to dance or not. The other option would be to do it myself with ipod and speakers but then I'd have to download a bunch of music. Any other options I'm not thinking of?
