Just over a week until my RSVP by date and here are my numbers...
48 yes
3 no
82 PENDING!
We decided to to e-RSVP through our wedding website to save some money and knew that meant that we'd have to end up calling the couple older people on our list, but I'd say 80% of my pending invites are between the ages of 18 and 35, so they should have no issue pulling the website up on their phone and RSVPing.
How close to your RSVP date did you get most of your responses?
