Our wedding is June 27, 2013. we sent out STD in Sept 2012, our invites went out last week with a RSVP date of 2/15/13 and a please book and place deposit date of 3/15/13. Final payment for the trip is due mid April. We figured that would give us a little leeway to chase down stragglers if needed in the end bc that us not something I want to be doing lastvminute!
