I have been to WDS and its, more or less, DHS only smaller (which is scary compared to DHS being not that big). Still, it should fine. They will probably stick it in around the Cars land. They already have the Crush Coaster which, in my opinion, was one of the best uses of the Nemo Franchise. Check it out on youtube. Its a dark ride similar to the one at EPCOT and then you ride the EAC through a spinning roller coaster. I really wish EPCOT would have this one! They could probably get away with it being the only roller coaster since they are not, well, educational.
It's gorgeously themed--really gorgeous, but the main visible additions are essentially flat rides with long wait times (90mn today) sort of read to me like they've essentially caught up with Parc Asterix and other neighboring parks.
Unlike A Bug's Land at DCA, the footprint is extremely confined (they're running into the Disneyland Hotel; the Flying Carpets are essentially right behind one wing of the hotel) so small that there's nowhere to sit.
Crush's coaster sounds interesting but I didn't have time to wait in line for it; I'll try to catch it during EMH (yes, they have Extra Magic Hours here). It is supposed to have the same video technology as the Submarine Voyage got a few years ago at DL. It *could* be a "game changer" but can't be the way that the Cars-themed Test Track going into California Adventure will be.
If you don't ride it, at least don't miss the sign for it (with a little ride vehicle spinning around eccentrically) that's just brilliant. I think it is Maurer Sohne's miniature demonstrator that I recall seeing at IAAPA when they started selling it a few years ago.
The land's not quite done yet. There's fresh pavement, and the exit to the area is through what used to be a parking lot for a very visible, unthemed existing EDSCA office building. I'm assuming that this is temporary and the land will expand if they ever make any money here.
My favorite thing--seriously--is the fencing. It's made of Tinkertoy-type parts (the plastic version, I think it was called Connex or something like that) made of cast aluminum. Even the long rod pieces are shaped and snap into the joiner blocks like the toy ones do. They are totally cool, I'd like to have a fence of the same material for home.
Funny story. First day I saw the new land, I noticed these ARRI 6K and 12K HMIs (big film/tv lights) set up all over the place, complete with not-in-very-bad-shape ballasts (power supplies); expensive modern gear unlike the old cast-iron Mole gear they have on the tram tour. And all of the lighting, even the ride lighting and landscape lighting, had gel (colored acetate used to color light for theatre) taped to it. I said to myself, "gee, they really went all out to make this look realistically like a film set!"
Turns out the lights WERE real--it was press day the next day and they had everything lit for TV stand-ups.
