Chris,
You may not have the answer (yet), but...
With the stalls, the center aisle stalls (I think they're #21-40) I'm sure only open on one side/aisle. So those of us "thinking" we'll be in Stall 21 and across the aisle from our friend in Stall 41, may ACTUALLY be facing stall 1? Do you know if that's the case?
