I think it would be tough for them to do this in Orlando. The corrals are currently the full width of the road. The median near the entrance to each corral is not flat, which is one reason the huge banks of the porta potties are staged back where the terrain is flatter. You can't put porta potties in the corrals or else there would be a hazard to people walking towards the line once the corrals begin moving forward. Stopping at the last one before the walk to the corrals and then again once you get to the ones at the corrals is the best option for those who don't want to zip over to the woods.
