OK -- DisneySea had Tokyo Bay on one side, and Tokyo
Disneyland on the other... built in less than three years.
I can't and won't address the cost issue. Maybe you're right on that, but I don't know enough about that to address it.
And I know it seems nitpicky... but it DOES seem to me like this is taking a long time, especially when you consider there's not a major E ticket attraction in the bunch.
And Circusland -- I mean that should take weeks to build. Goofini is already there. Dumbo is a traveling carnie ride that they can unload off a truck and building in an afternoon. Sure, they're going to build some tents and games and all, but this shouldn't that long.
