This was around 9-10 pm. In the recording you can hear a woman answering the door for a guy and saying "Nice to meet you", then some unintelligible conversation. I think that they were 2-3 doors down from me. The original recording was much longer than this, but I mainly cut out people who were talking in the hallway, and a guy who wouldn't stop singing in his room. Shortly after meeting, the sound of their lovemaking started to echo through the hallway for everyone to hear. I wish he had lasted longer because she was really getting into it. I didn't capture this in the recording, but after they finished they stepped out into the hallway and she sort of awkwardly explained to him how to find the elevator.
Unfortunately, I didn't catch a glimpse of them. However, I think this was a hotwife situation. I was looking for some action myself that night and saw on a distance-based app that there was a couple hosting in the hotel. I did try to message them to see if I could have a turn too, but I guess that guy tired her out

Anyway, hope you enjoy! I know I did.
