On a work trip to Mississippi last year, Jason GaNun wound up trying three different hotel rooms to get some peace and quiet before a busy day — and none of them did the trick.

In the first one, he said the “ancient” air conditioning unit was one of the loudest he’d ever encountered. When he moved to the second room, it was the refrigerator noise that got in the way of sleeping. And next to the third room he tried, other hotel guests were throwing a party.

“I could hear everything they were doing,” said GaNun, a project manager for a demolition company in Pennsylvania who travels every other week for work.

For Lindsey Maness, the menace during one hotel stay for work in Austin, Texas, was a noisy elevator near her room. Seven months pregnant at the time, Maness could hear the “dinging” of the elevators opening and closing all night. That wasn’t the only issue.

“The walls were paper thin, and I could hear people in the room adjacent … chatting until very late in the night,” said Maness, who now works for the National Sleep Foundation. Far and away, it was “the worst night of sleep” she’s had at a hotel.
