If you have the materials, feel free to light the potty bank near where you will be camping. This will be a HUGE community service for those on the night party shift. The banks out by the Man and the Temple will be lit, but those within the City need luvin too. One can surmise the dimensions from these bits of info: 20 porta-potty units in a line, 2 lines back-to-back per bank.
Good luck with whatever you choose to do.
