You should call back ASAP. I am getting married on October 31, 2011 and was able to book a shoot for the second week of November this week. It was the only one available that fit with our honeymoon schedule and all the tours and dining we have planned, but the woman I spoke to said that they just recently changed it to 2 couples per shoot instead of one. When I first inquired about the MK shoot I also was told it wasn't avaiable and it broke my heart. I hope this helps and one is available. I am really in it for Haunted Mansion photos and have not even been able to find out if I will be able to take them due to construction at that time. I was told to inquire the day of, which kind of threw me because it is a large motivator to shell out the money.
Best wishes and congratulations.
