Hong Kong Disneyland is such an underrated park. I'm glad it's getting this.
Hong Kong Disneyland is a nice park. The layout is very much like the Anaheim version with the same castle.
Also, for a park without a Star Tours ride, using a tried and true (and very fun) concept for an Iron Man ride is a terrific idea. I have no problem with the decision. Plus the random elements of Star Tours II should allow for plenty of cool Marvel villains to be part of the show.
I've always thought a version of the Mission: Space ride system would be the best way to do an Iron Man ride. The individual little screens, with the Infinity-Viz technology would be so perfect. Each person has their own screen, really making each person feel like they're in their own Iron Man suit. The storyline would work because we know Stark now has many, many suits in his collection. Also, the screen from Mission: Space seems like it would most accurately replicate what Tony Stark sees from his mask. And no ride has ever captured a more realistic replication of the sensation of space flight than Mission: Space. The only change I would make with the system would be to have the Guests laying down and facing forward, as opposed to sitting and looking up at the screen like on Mission: Space.
