Frankly, I'm surprised that more people aren't talking about these upgrades. As far as dark ride updates, they're pretty significant. From my recent visit, there was a WHOLE LOT of love poured into the revamped Alice. It's really quite amazing.
First off, everything's been freshly painted and touched up. Everything's brighter, sharper, weirder. First off are TWO (2!) brand new fully animated Cheshire Cat heads done with the same kinda high definition projector stuff that's used all over the Hunny Hunt attraction in Tokyo. This is much smaller scale, but still very vibrant and beautifully integrated. The smoking caterpillar now breathes out working 'smoke' and has it form in full-color full-motion high definition animated letters. It's absolutely awesome, and is the best this effect has ever looked.
Did I mention that every single flower AA is working, mouths all synced to the Golden Afternoon? This is the first time I've seen it working it over 10 years.
As everyone has mentioned, there is a brand new (again, fully animated) hedgehog-as-a-bouncy-ball sequence, but they still haven't lit that new scrim they obviously installed. I'm guessing it will be lit up to match the vista of the Queen of Heart's castle and her Red Rose garden (which is the next scene.) Anyone know about what they're testing on those new scrims?
And finally, the trippy descent to the "Merry Unbirthday" now also has an upgraded projection: a brand new, fully animated "cloud circle thing" , surrounding the Cheshire Cat's laughing (and rocking) disembodied head.
Nice Disney!!! These are the wonderful SMALL BUT IMPORTANT details I remember of the Disney parks of my youth. with the upgrades, Alice is a serious contendor to tie with Peter Pan for best Fantasyland dark ride. Regardless, it's now the most high-tech ride by a very large margin. And it DESERVES it!!!
