As much as we all love all of the information and inside scoops that
@WDW1974 provides for us here, to be fair the latest MiceAge Update fleshed out a lot more details and included new information than the Spirit offered here the night before.
For example, WDW1974 said this on Monday the 18th at 7:06 P.M. Eastern time:
"Both DCA and HKDL (and looks like DLP can be added now thanks to a kind source) will be getting temporary attractions that will very likely be there for years. And I use the word 'attraction' very liberally here. Think meet-and-greet-and-gropes and singalongs and things of that nature. They will not be replacing anything right now, just utilizing existing and or new real estate." - WDW1974
That was a scoop, and we loved it! But that's all the information he was able to share in this thread, in order to protect his sources and/or honor his friendships within Disney. And for that we respect him and thank him.
About eleven hours later, at 3:00 A.M. Pacific time on Tuesday the 19th, a MiceAge Update was posted to their website. Here's the more fleshed out and specific information MiceAge offered eleven hours after Spirit shared what he did:
"Taking a cue from the successful Frozen Summer Fun promotion they pulled together very quickly out at Walt Disney World, a new Frozen offering will be shoehorned into DCA for this Christmas season. Setting up in, you guessed it, the backlot area of DCA’s Hollywoodland, the characters from Frozen will be moving in for the holidays. An indoor ice rink and character meet n’ greet will be installed in Stage 17, while next door the Muppets will go on hiatus (again) and the MuppetVision theater will be repurposed for a small stage show and Frozen sing-along. Frozen décor and set pieces will be plopped down around these two venues and take over some of the existing Mad T Party facilities, and the existing Studio Store nearby will be turned into a Frozen merchandise headquarters. This will create a Frozen miniland of sorts in DCA, and should help take the pressure off the Frozen frenzy currently found in Fantasyland." - MiceAge Update
So there's a whole bunch more information there than what WDW1974 was able to offer. From MiceAge we got the exact location, the planned offerings, the venues to be used, a timeline aimed at the Christmas season, and the scope of the overall project.
The rest of Tuesday's MiceAge Update was so Disneyland-centric on stuff coming in the next eight months, focusing on the new night parade, new fireworks, dark ride upgrades, breaking the news that Toontown would become a "show building" for a Star Wars E Ticket accessed from the Big Thunder Ranch area, plus fleshing out the rumor of the new Marvel Land coming to California Adventure behind Tower of Terror that MiceAge already leaked a couple months ago, that I'm not sure much else could be compared to anything @WDW1974 has posted here.
I love me some juicy global gossip from @WDW1974 threads on wdwmagic.com, but the MiceAge Updates have been fleshing out the Anaheim details for over a decade. This latest update from MiceAge is no different.
