DHS is obviously not designed to handle the crowds MK is capable of. But could the demand to visit DHS surpass MK? It will be interesting to see what Disney does to spread out the crowds between the 4 parks.
Not that I'm an expert but MK reports around 7,000,000 more guests per year that DHS. So, I don't think demand at DHS would come close to that. I am still puzzled by "we have all this land" and yet it is used inefficiently.
Either way, I am about as excited as MMRR as the two Star Wars rides, primarily because I figure that I'll be able to get on this ride more easily and it looks really fun.
