I don't know if this has been mentioned, but I find this whole set up remarkably out of step with everything Disney's ever tried to do.
From their inception Disney Parks have put on a show for park entrance. Traveling through a tunnel and suddenly being transported to a fabulous new world. Walking under an incredible monument and being invited to the epicenter of science and technology. Embarking into deep rain forests to journey and find one's self in a beautiful natural world. Entering a soundstage... I guess we could forget about WDS
In the above, show comes first. A message is relayed to the guest. You're not in the world you knew. Welcome to a Magic Kingdom of land or sea, an Epcot, or a Kingdom celebrating nature with a message it wants to share.
Much like a well written essay, the opening street sets the scene, establishes the thesis, and transports the reader (or in this case guest) into a whole other world.
There have been examples of park gates not found at the main park gate. Hotels like Miracosta and Grand Californian serve to soften the transition, and are actually helping tell the story of their adjoining Parks while the guests explore, sleep, and relax. Subtle yet effective. The entrance into World showcase is slightly less effective, but with ample park space and a more drawn out transition it makes for an enjoyable and fun experience entering the park. Disneyland Monorail also builds suspense and sets the stage impressively well in Tomorrowland and Fantasyland. The worst alternative park entrance ever created has to go to Paradise Pier's entrance, which was pathetic. Of course the same could be said of the host land at the time so...
Even in those cases attempts to soften the transition or even more effectively reinforce the story are carried out.
Now this bus system. The areas of entrance are not purpose designed. They're actually slightly repurposed backstage areas. Instead of attempting to tell story with this transport option they're simply plopping guests into the middle of the park with no thought to theme.
Letting guests out at Harambe or Tomorrowland is akin to asking someone to just start reading an essay right in the middle. The guest misses the purpose and thesis. You're implying the opening isn't worth it or is a hassle to be avoided. The reader should just get to the best parts in the body of the work.
Any mature adult would realize that without context, the best parts of a book become almost meaningless. There is no understanding of why the events are taking place. There is no emotional investment. There is no higher purpose to the events happening. It's simply a ride or themed area that could exist anywhere in any city.
The power of theme parks is the fact that a whole bunch of disparate worlds and adventures can tell a cohesive story. Skipping proper story order and experiencing the events out of the intended sequence cheapens the experience and leaves it's purpose distorted.
Ironically in the guest's pursuit for checking things off a list, they miss any greater message that's trying to be sent. That's part of the reason theme parks are seen as a lesser form of entertainment. When the experiences are looked at through a narrow lens of rides instead of the broader picture of a whole experience.
This is a clear case where being affluent backfires and produces an inferior experience for the guest. I'd expect someone at Disney to realize that as stewards of parks like these, it should be their responsibility to uphold their integrity...
Disney's Animal Kingdom clearly suffers the most from these transport changes.
So to end this, I also have to join the chorus of people amused that they're exposing backstage areas. So 2016 Disney...
It is worth noting that the VIP tour guided guests could already do this. I laugh at the idea of paying hundreds of dollars to skip show you're paying for. Such is life.
