"People have sex in those bathrooms all the time!" says one employee. "They’re completely see-through. [Neighbors] across the way can even see you peeing. We get complaints about it, but whatevs."
"Stairwells, 100%," confides one former reservationist. As if taking the stairs in and of itself wasn’t enough to get your heart rate going. While it might not be the most comfortable, your safest bet is to do it standing on a corner landing, equidistant from the doors to the floors above and below you (or so I've heard). This gives you the most time to act natural in case someone shows up. Keep in mind, many stairwells are surveilled by cameras. "You should see the shit the security guards would show me," says our source.
Stopping an elevator in a busy hotel for a quickie is a dubious proposition at best, but people do it. "Drunkards would always pull the emergency stop button," recounts one former concierge. And unlike stairwells, elevators are much more likely to have cameras in them. To decrease the likelihood of your bits winding up on the internet, you might want to try the service elevator, explains another employee, since there "aren't always cameras in there."
