I have been to the APS Synchrotron quite a few times and realized that there are a couple tricks of where to sleep, if you don’t stay at the Guest House. I often see newbies trying to do the head on the table approach, but in a rolling chair this can be tricky.
So what to do?synchrotron conference room Sleeping at the APS Synchrotron

1) Sleep on the floor
Pro: plenty of space
Con: the floor is concrete
If you are going to go this route then at least sleep on a coat or put your head on a bag (bring a pillow!).

2) Conference room (located along outer rim of the building)
Pro: decent space, very thin carpet, darker and less noise than being near the beam lines
Con: synchrotron couch Sleeping at the APS Synchrotrongroup members may think you have disappeared, if you don’t let them where you are sleeping

3) Couch
Pro: located near the beam line and a lot better than the floor
Con: bright, few around, maybe on the shorter side if you are tall

I have not been to Brookhaven, but here is a tip from @modernscientist:
