I'm asking because to hatch eggs, it takes a certain amount of steps to hatch them. In Gen V, I would always use SkyArrow Bridge because it was simply too easy to hold up in one direction, then down in another direction.
What's the longest possible route either horizontally or vertically in one direction (just holding one direction button) in all of Pokemon X & Y?

Lumiose City Centrico Plaza
This plaza surrounds the Lumiose City Gym in a circle. If you hold left or right on that screen you can go forever.
