I was going to try to suggest one of those aerial cable tram rides like they used to have in the Disney parks. I couldn't find any acquisition and maintenance costs for one of those though.
When the walk from the parking lots (especially Orange lot) is added in, you could be looking at a mile walk to get to the center of the activity.
There's not much in the way of east-west transportation. Maybe a run between the main entrance to Boeing Plaza would help. That taxiway is wide enough so the added vehicle probably wouldn't interfere with foot traffic much.
The real problem is that paying vendors wouldn't like being bypassed.
Maybe we should talk with those Hyperloop people.
