What people fail to realize is that this bypass has been in use for nearly 2 decades already, this is a POSTIVITE thing because the company is acknowledging that guests should not be in a backstage area, regardless of the purpose..
A few facts:
1. The bypass will not be open at all times (just like now) it will only be open when needed (heavy days such at 4th of july, Christmas, and higher capacity days)
2. if you approach the main street area from tomorrow land, you likely won't have a choice where to exit.. You will be forced to go down this path if you are leaving the park.... This is how it's been done for nearly 20 years, so any grandiose plans of "I;m still going to go down main!!!" are not going to happen unless to circle the entire park as come up main from the Crystal palace side..
Again, it's not going to be open everyday, just when needed.... This is simply a theming of an area that guests have been pushed through for a long time anyhow... All positive.... And Traffic flow like Disneyland would simply not work... Disneyland doesn't have the amount of guests in a day that MK does..
