We had the unfortunate experience of being next to a room in which the occupants stayed up past 2:30am - going in and out of the room, slamming the door, which reverberated off the wall/headboard of our bed, and talking so loudly that we could hear everything they were saying. They also had children that were up that late. When we finally called down to the front desk, the employee said they were aware and were about to come up - which was long after all the commotion got going (it started around 11:00pm). I know the hotel can't control for people's initial inconsiderate behavior, but this was egregious, we lost hours of needed sleep, and it ruined our experience.
