Line out the door

5:30 am: I try to make a mad dash to the laundry room/spare bathroom and there is a line of guests at the coffee machine. (The laundry room is just past the guest coffee area.) When do they sleep for Pete's sake?!

My keypads text me each time their enter their code, so I know when they come and go. Well, I know when they come in, don't know when they leave. But on multiple occasions I've seen them enter their code, returning from outside, about 10 times in a 20-minute period around 2 or 3 a.m.
I have no idea what they are doing. I can see once or twice in the night, going out to smoke or check their car, but not 10 times in 20 minutes. I always fear they are carrying stuff out of the inn to fill a UHaul, but have never lost anything. I have no idea what the're doing, but no, it seems some of them never sleep!
