I know I sent out my invites early- about 80% of the guests are out of town- but I'm starting to be concerned about the lack of RSVPs in the three weeks since I sent out my invites. I made it very easy and instantaneous with electronic RSVPing on my wedding website, but I've only gotten 11 RSVPs so far... and most of them are people in the wedding party.
Besides the obvious question of whether I went too crazy with electronic RSVPs (it's too late to change that now), I pose the question of when most people do RSVP... Do more people RSVP in the middle of the time between when they get their invites and when the response is due? Or do more wait until the last minute?
