We sent the STD in July and just sent an email with our website since the postal stamp on the STD card covered the website address. Anyway, my guests need to start booking asap. 50% of my rooms must be booked by mid October and the rest by the end of December. I must release the unbooked rooms after this date which means my guests can still book but will not receive the discounted room rate. I have a friend working on my boarding pass invites and will be assembling them with the help of my high school gf in 2 weeks. I am going to do a RSVP through my website. Like someone mentioned - you know if a person is coming if they booked!
