I used the contact us link from disneyworld.com to ask why 2007 rates were not loaded yet, specifically room only rates, and after being persistant and 4-5 emails, I was told they basically have no idea - or for some reason refuse to say.
Here's what I got:
"What you are experiencing is not a glitch. 2007 pricing and availability has not yet been programmed onto our website. A release date has not yet been announced."
Pretty late for a big travel company.
