Nope, it was retired. (Not because it wasn't popular, just because they decided not to fund it I guess?) Soon after they gave out a VMK pin for about a week and now they give out fast passes.
I know that the Disneyland ones were very popular and would fill up very quickly, but here at WDW it was not like that. There were times when they didn't have the tour because there weren't enough people who would sign up. I think what it came down to was money untimately.
WDW was different than DL because it would get mostly tourists.. and you had to sign up at city hall rather than VMK central... thus making people confused.. lol
I did both tours.. (WDW & DL) and enjoyed it... it was fun, and interesting.. though now it would be interesting if brought back to see what they do instead of showing the future frontier land project... (No photos please.. these are secret.. lol)
