I'll add some more info as @Surf and Snow did.
Test date: 4/13/18
Test location: Raleigh, NC (McKimmon Center at NC State University)
Table set-up: Large 2.5' x 10' folding table, two people per table. You could keep books on the table so long as they were standing upright or placed in such a way that the proctors couldn't easily see your test. Bags, shelves, boxes, etc had to stay on the floor. Food and drink could not be placed on the table, not even a bottle of water. I had a folding wagon that I rolled halfway under the table, this kept it out of the aisle and my books were easily accessible (photo below). There are multiple rooms in the McKimmon center, two big rooms (room 1 has about 330 people, room 2 has about 150 people, rooms 3-5 have about 40 people each). You don't get to choose which room you are in, you are assigned. Room 1 was laid out in columns with the center columns being two tables together, so not every seat is on the aisle. The proctors were pretty nice, it's a slow process passing out and collecting all the materials so expect to be patient.
Time keeping: There were clocks in the big room 1, but I couldn't see it well enough from my seat for it to have been of use (I have 20/20 vision, do not wear glasses or contacts). Plan to wear a watch or bring a clock to go under the table. You cannot set a wristwatch on the table, it must go under the table or on your wrist.
Parking: Arrive early, there is plenty of parking but the later you arrive the farther away you'll have to park. The parking lot is on a hill so if you have a rolling suitcase/wagon/crate/etc. be prepared to pull it up a hill toward the building.
Lunch: There are lots of places outside and inside to eat lunch. There's a cafe on site but it may or may not be open. There are lots of fast food joints close by. I packed my lunch and ate with friends at a table outside in the sun, it was a nice break. I didn't want to risk leaving the site to get lunch, just in case.
Security: The testing rooms were closed during lunch. You had to use your authorization and ID to get back in for the afternoon session. Don't leave your keys inside if you left your lunch in your car, I saw several people unable to get back in to get their keys and couldn't get into their cars during the break.
Restrooms: There were only two restrooms and one of the ladies rooms was closed for some reason. The lines got a little long but luckily there's a lot more men who take this exam than women.
