Would you mind if I say that I'm glad you're addicted? ;-) But seriously, thanks for your kind words!
No, I don't know why the calendar isn't out (see below for some potentially related news). I had the same issue with our reservations in December. They WILL come out, but I know the waiting is painful! In my case, I simply used last year's calendar (you can find them on several unofficial sites -- I used tourguidemike.com) as a guide. It worked perfectly, as very little changed from year to year. If you do this, be sure to compare similar days of the week (e.g., second Wednesday in January), not exact calendar dates.
You don't mention your exact dates, but your question gives me an opportunity to share some exciting news that Mickey (or was it Minnie?) officially shared with us yesterday. Here is an excerpt (it only affects you if your dates go beyond Jan. 25)...
"The reservation system used at WDW for booking dining, recreation and tours will be undergoing an "extreme makeover". This new reservation system will provide Guests opportunities to book multiple reservations during one booking session and Guests will also be able to make dining reservations online at disneyworld.com as early as December 2008.
During this system upgrade, some changes will be made to the current booking horizons. The normal 180 day booking window will be reduced starting July 31, 2008. Reservations for dining, recreation and tours will only be accepted through January 25, 2009 for a short amount of time. The good news is on October 24, 2008, the anticipated upgrade completion date, reservations will again be accepted for the normal 180 day window or April 21, 2009.
Reservations for Victoria & Albert's, Cinderella's Royal Table, and Chef Mickey's will not be impacted by these changes. These three venues will continue to observe normal booking windows."
Thanks again for your great questions. Please keep them coming!
