I just want to mention again, in case there is lingering doubt... there will be some sort of parade or new version of the Cavalcade. All signs are pointing to it. I don't think there is any question about it. It may still be a mini-parade deal, but revamped (more likely), or it may be a full-fledged extravaganza (less likely). But there will be something. While I hesitated to add the Frightfully Fun Parade to my posts on page 1 because it hadn't been officially announced in the traditional sense, I know that there will be something.
The first clue was the wording on the audition site a few months ago, which indicated that performers were needed for a parade of some sort during Mickey's Halloween Party (Viva Navidad was also mentioned in the same listing, so that event is likely going to be revised and enhanced a bit too, for the holiday season). If there were no Cavalcade or parade coming up, there wouldn't have been a listing on the audition site.
The audition site is how I found that Olaf's Snow Fest was returning for the holiday season last year (the lute players were a dead giveaway), as well as how I knew that A Christmas Fantasy Parade was returning last year (even though there had been some doubt because of Paint the Night). The audition site was also where the first signs of Paint the Night preparation appeared, as the performers were being lined up.
The next clue about a Halloween parade or cavalcade was in the Disneyland press release that came out in July -- "The Headless Horseman of Sleepy Hollow rides his ghostly black steed and carries his flickering jack-o-lantern through the heart of Disneyland, heralding the arrival of Mickey’s Halloween Party character cavalcade, presented on the 17 nights of this special party." Now, granted, the wording there makes it seem like it's just the regular ol' Cavalcade, but at least it would be something.
The next clue was the reference to the Frightfully Fun Parade on the Disneyland website, in conjunction with the "Halloween Dinner" at Blue Bayou this year. I think it's a catchy new name for a re-imagined Cavalcade. In other words, I don't think we are getting a full WDW/Boo to You-scale extravaganza, but we are probably getting a better version of what was the Cavalcade. ...Something more like a parade, but maybe missing a few bells and whistles here and there.
And now, of course, other clues and bits of evidence are popping up to support a parade or Cavalcade, cast members are mentioning it, etc.
In any event, I don't think the Headless Horseman is just going to be galloping back and forth without purpose. His appearance will lead to something! I think that the Parks Blog could probably stand to release this Cavalcade/parade info to us a tad sooner -- I don't know why there has to be a delay -- but maybe they are holding off on mentioning the Frightfully Fun Parade until they do the blog about the Blue Bayou Halloween Dinner, as the Parade will be a selling point of the dinner.
