Shower RSVP vent

I currently have 8 people outstanding. The RSVP date is Saturday. There are 2 numbers and an email address that they can respond to. Is it so difficult?
I had to put on hold ordering my favors because I dont want to end up short.

Sorry hun...just wait til the wedding. My rsvp date is Sunday and I am still waiting on 69 responses...
