I was thinking early June. I always feel like I'm doing things to early - then again, you can never be too early! When are you sending out yours?
end June/1st week July
thats weird because my wedding coordinator at the venue said I should send mine out the first week and May and request them back by mid-July, so I have 2 months (wedding is September 23) for stragglers to respond and get seating charts and split menus in place.
Sent mine out in June...can't remember exactly when. MIL told me I should wait until three weeks before we get married to send them out!!!!! Oh and I should mention we're getting married Labor Day weekend!! She said people will forget LOLOL should have told her I'd send her a reminder card just in case..... hahaha!
Just sent ours out last weekend. July 16th, our wedding date is September 29th. I read that you only need to give 6 weeks notice. We had already sent out save the dates, so I thought a little more than 6 weeks was a good option. We've already recieved some RSVP's!
We are getting married 9/10/11 and sent ours out on 7/16/11 and giving people till 8/5/11 to respond. Our caterers only need our final numbers a week before our wedding and we aren't doing a seating chart.
I sent mine on June 5th-ish, with an RSVP date of August 5. I have heard back from 91 guests and have 60 attending so far (I know of several others coming, but I want their actual RSVP, and most of those not attending are kids of couples). I'm still waiting on about 140.
