knitgirl - you're definitely not doomed. i might even just skip STD's if i were you though and send invites instead (if you were planning on doing both) .. (ie. FI and i send email STD with plans do send invites later, but everyone who is coming have already booked so we're skipping official invites for the wedding and will only be doing some for the AHR once we return) Regardless, you'll just want to let people know asap so they have a chance to save
