Hi Tara! I also sent save the dates out a full year in advance. Our wedding is February 2014. I plan to send the formal invitations out in August and have an RSVP date of October. The rooms/ rates we reserved are valid until October 27th, and I will mention that in the invites as well as have more detailed information about the resort and a schedule of events. Just an FYI for future brides... From my experience so far, and I'm not sure if anyone else ran into the same issue... But, it seems to me that some guests are a little confused about when to actually book their room. I get comments sometimes from people saying that they are waiting for me to send the invitations out so they can book their rooms, which they should not have to wait until the invitations in order to book. On the back of our save the dates we have a note saying 'We have reserved rooms at special rates, please contact...' followed by my travel agents contact information. I did not have detailed information about the resort such as pricing, etc. and I think this caused confusion for some people for whatever reason! I think I'm going to take MMK's advice and send out a short email or facebook message as a formality before sending out the invitations, just to let everyone know a bit more detail such as pricing, hotel information, the rates deadline, etc.
