Activity for Lyndsey

Hey! I'm getting married September 10th. I'm not sure if I should have two songs during the ceremony or just one for the unity candle. We have one for the wedding party, and one for me. I don't want the guests to get bored, but I don't want it to go...

Does anybody know of cheap catering places?

Does the bride pay for the flower girl dress or do the parents of the flower girl buy it?

Do weddings have ushers these days to seat people? If so how many?
