Maybe everyone is tired of seeing these posts, but I had to join in.
Yesterday was our RSVP due date, and this morning we were still waiting on 74 responses... out of 160ish guests invited. We mailed out invites early May, so they had about 6 weeks to respond. We also did only online RSVPs, so there's no chance of their replies being lost in the mail. Most that we are waiting on are tech savvy, so that's not the issue either.
What's also fun is that my final payment for our alcohol is due tomorrow, so they want me to send them a final count today so they don't overcharge me (which can be adjusted up to 2 weeks prior & I would get a refund if necessary). It's just a little difficult to give them an idea when we're waiting on almost half of our invited guests.
