I took the Oct 2018 PE exam in New Orleans. I didn't find it to be that bad. We were in a large room (pretty high ceilings) at the Pontchartrain Center. Two people shared a 8 foot long table, so each person had half of the table. And there was enough space between the tables to pass. I could imaging that it could get cramped depending on the number of people they tried to squeeze into the room, but we had ample space.
The issue that I had was that the instructions that came with your admission ticket said no food was allowed to be brought in to the Pontchartrain Center, and that the concession stand would be open. But the concession stand WASN'T open, and the proctors DID allow snacks, but I didn't bring any because I was trying to follow the rules. There was no clock, so you had to bring your own watch (no smartwatches or fitbit). That's crazy to me that there's no clock on the wall.
All that being said, I've still heard that Baton Rouge is a better setup.
