I am pretty sure its there to combat with Cirque du Soleil at Downtown Disney. Not thats its a probalem or anything, but they are more or less the same price admission (Cirque might be a little more). Hey, bringing Blue Man Group to Orlando is always a plus!
A majority of the seats in the Cirque show are good!
Anyway, Blue Man's group's main purpose is to give a "show" to Citywalk I mean look at the similarities
Blue=CirqueEmeril= Wolfgang PuckO'Brien's= Raligan RoadHardrock= Planet Hollywood
Thus Blueman Group is a great addition to Citywalk!
