Did you get manager approval?
I may be completely off base on this post. I don't mean to be rude either.
I think you may want to check with your manager before you start advertising yourself as a Cast Member running a Disney related Site (Tomorrowland). You may have signed something that prohibits you from speaking as a representative of the company on such a medium. You may also want to check with your union steward because your opinions might not represent the opinions of all your fellow operation cast members. If your site is just purely an informational site, then I believe WDW has that covered on its official web site. They do an excellent job of attraction descriptions there.
I know there is a very thin line between what is confidential knowledge / what is knowledge that can be shared by the public. Sometimes just because something is common knowledge of all the employees of a company does not mean it is intended to become common knowledge of the public. (Ie. You suggested that a Lilo & S Attraction may be replacing a current attraction - I don't remember the WDW Company officially making that release as public information.) Remember, WDW is a Fortune 100 Company. It is one thing for consumers and fans of a company to publicly speculate and critique a company in a public forum, but I think it becomes a whole new situation when you publicly announce yourself as an employee (representer) of that company in a public forum. I know this Tomorrowland Page has been created with the best intentions behind it, but you may want to exclude promoting yourselves are Cast Members.

PS It is also a little about what Joe Torre said about David Wells' (both NY Yankee's Employees) new tell all book. "It is all about preserving the sanctity of the club house."
