Anyone not using a DJ? We are considering doing a playlist & putting someone in charge of the I-pod. I have mixed emotions about this..on one hand we are already spending a lot of $ & I do not want to ruin it by not using a DJ, on the other hand I almost feel like it's a waste of $..I have heard some say a DJ can feel the room & keep things moving but I'm just not sold..What do you guys think? Has anyone ever attended an "i-pod wedding"?
