How long is everyone waiting to start calling people that have not sent their RSVP cards back? Our deadline is this coming Saturday and we are still waiting on about 150 people to send their cards back to us! My dilemma is that I know there will be some stragglers but I need to get a count to the caters and do not know how long I should wait before I pick up the phone and call people? Thoughts or what are you doing?
