Wedding Date

I'm seriously considering Sunday May 30th, 2010 for the wedding.  It has some advantages - lower prices because not yet June, its close enough to June that the weather will probably be good, and its the weekend of Memorial Day, so my Sunday wedding is effectively a Saturday wedding.  However, I'm worried that Memorial Day will make it more expensive and difficult for people to travel.  Right now I'm thinking that the benefits outweigh the potential negatives, but I'm super indecisive, and, having a actual wedding date scares me.
