To be fair I actually think SDMT is the more complex build based on the rock work, but yes Universal crazily invested in 24/7 manpower.
I don't see why Disney can't spend a little extra to speed up build timelines, surely the positive benefit of having a new attraction earlier would pay it off. SDMT really should have been opening this summer (and they should have had something major in the pipeline in the works for Summer 2014 - but I digress....)
This ride is pretty great. I actually genuinely like EVAC the character they create for this attraction, I think that was what I was most surprised about.
