Queue
The WDW queue quite possibly has some of the worst theming I have seen for any theme park attraction. It shows all the failures of the theme park themed to a movie studio format that was popular during the time.
However the building is still bright and colorful. It tried to be an inviting front to this theater experience. And in some ways, it's even a little charming. The front will age itself poorly however, when one of the shows advertised (Rolie Polie Olie) got removed from the experience (and as far as I could find, the front of the building wasn't updated to reflect the change).
In the queue were hanging CRT TVs that played clips from various shows and a screensaver-esque animation of the Playhouse Disney Live logo bouncing to instrumentals of various Playhouse Disney theme songs. Sadly all of these instrumentals are lost (as far as I am aware of anyways). Before entering the interior, the guests are instructed to yell out Jamie's (the host of the show) name to enter, once this happens, the TVs will reset/progress their loops and starts playing the screensaver loop.
Whenever the CRTs loaded the screensaver loop there was a little honk noise before playing, which I found oddly amusing (around 27 seconds in if the video doesn't work for you).
The DCA variation of the queue is marginally better. It fits the rest of the land well, and doesn't look like a box with Disney characters slapped on the front. It's a little eye-popping, but then again the rest of the land wasn't themed too well, so it's somewhat excusable.
One of the coolest features of the DCA queue line was the rotating sign, which showcased all 3 of the shows that were featured in Playhouse Disney live.
Sadly by 2008, the rotation feature was no longer in operation. The sign was still updated though to include the new characters.
In the queue were various TVs, some were themed to fit the rest of the land while others were themed to look similar to the designs seen in
program bumpers on Playhouse Disney. These TVs would play clips from the shows from the network and didn't have the strange screensaver WDW got (unless I'm mistaken and both DCA and WDW had the clips + the screensaver). These TVs were also flatscreen, which is mind-boggling to think about, but that's way off topic.
Interior
The interior is quite impressive. There's a lot of lights, projections, catwalks (since the WDW version was a catwalk bar, it's a genius way to reuse that), bubble machines, confetti machines, and a bunch of other theater stuff that IDK the names for. While waiting for the show to start, guests will be greeted to a collection of songs from Playhouse Disney shows (around 1:30 in the video if it doesn't work for you), mostly from Bear in the Big Blue House. This will be a mainstay for all other versions of the show (just with different songs playing).
The stage has a mechanism on top that pulls the "house" in revealing the giant storybook set. From there, the host "Jamie" opens up the pages of the book to reveal the other characters.
Each of the storybook sets are visually impressive, while minimalist. Special mention goes to the Book of Pooh set, which pops open just like a pop up book. In 2006, the Rolie Polie Olie set was replaced by Jojo's circus, the only major change to the Bear format of Playhouse Disney Live. If you want a hot take in this strange write up, personally I prefer the Rolie Polie Olie version, but that's mostly out of bias as that's the version I saw live.
The true stars of the show: the puppets!
These Puppets were AMAZING, they were so well done. Screenshots and videos does not do justice on how high quality these guys were. Sadly, that's the only way to experience them now. From my memory, I specifically remember the Bear costume being huge, he really towered on that stage. And he had all the fluent emotions of the one in the actual Bear in the Big Blue House show on TV. Another 1:1 to compare with are the cast of The Book of Pooh, which look just like the ones featured on their show.
The original Playhouse Disney Live while having a short run (2001 - 2006 for WDW, 2003 - 2006 for DCA), was loved and remembered by many kids and their parents. During performances you could hear audible cheers and wows from all the age groups. From personal experiences, whenever talking about old Disney trips my Mom would always bring up seeing Rolie Olie Polie up on that big stage. But of course, all things must change, and with how fickle TV is so would this show.
