Since they're expecting quite a demand for the Weeknd, they need all the queuing space they can get. Looks like bugs will enter at what was previously the MIB tent entrance/exit and then wrap around the MIB show building. The other tent might enter at the same location but the switchbacks shifted to where the express queue for the north tent would have been.
Would improve the exit as well since they can use one of the old house entrances as an exit.
My feet already hurt, but I would rather be walking than standing still in a switchback.
