I sent out save the dates the first week in August, and no one has booked yet to my knowledge. FI's family is even waiting to put down a deposit on their rooms (eek). I put an early bird RSVP tool on our website, and no one (other than my mom of course, lol) has used it yet either. I've had people tell me either that they wouldn't miss it, or that they're definitely trying to make it work, but neither of those is a sure thing in my book! I think I will send out invitations by mid February at the latest. Our room block is only held through March 22, so I may even send them a bit earlier. I'm interested to know what everyone else is doing too!
