Yesterday was my 180 day. I had no trouble using the Disney website to book our reservations. I think I logged on around 5:20 am Chicago time, which was 6:20 Eastern. I made all my other reservations first, since I didn't really plan on trying for BOG. Then I decided to see if it was available for one of our free days, Dec 2nd, and it was, so I booked it. Now I'm really glad I got it, since in my heart I knew I really wanted to go there. My confirmation for BOG was sent at 6:06 central time, 7:60 Eastern, just around the time the phone in reservation line is open in Orlando. I think being able to get the reservation in before the call in people did might have helped.
