You've likely run into these offenders before.

No matter how much prep and planning we might put into our vacations, there's one factor that's pretty much outside of our control: our fellow travelers. Hotel neighbors can have a significant impact on our stay—from the couple expressing way too much PDA in the hot tub to that chatty Kathy who won't stop talking in the elevator.

The etiquette violation Americans find most irritating? Inattentive parents, according to Expedia’s new 2015 Hotel Etiquette Study. That’s right—parents who let their kids run wild topped the list of the most aggravating hotel guests. The study, which was conducted by an independent market research company GfK, asked 1,022 Americans to rank behaviors displayed by their fellow hotel guests. Below, the full list of behaviors people find downright annoying:

1. Inattentive Parents: 67%
2. Hallway Hellraisers: 64%
3. Complainers: 54%
4. In-room Revelers (noisemakers nearby): 52%
5. Bickerers: 26%
6. Poolside Partiers: 22%
7. Loudly Amorous (indiscreet lovemakers): 21%
8. Hot Tub Canoodlers (amorous couples in a public hot tub): 20%
9. Business Bar Boozers (sloshed business travelers): 12%
10. Elevator Chatterbox: 6%

The survey also polled participants on their tipping habits, with more than one-fourth (27 percent) of guests reporting they do not tip hotel employees at all. Out of all hotel employees, housekeepers are tipped the most (perhaps because 74 percent consider room service to be "a luxury").

But poor tipping isn't the worst of our offenses, according to the study. Twenty-six percent of guests have hoarded toiletries to take home with them, while 9 percent have sneaked extra guests into their room. The good news? Only 2 percent have deliberately eavesdropped on neighboring guests—and more than half use their towels multiple times for environmental reasons.

"While etiquette violations differ, they tend to come down to the same behavior: whether or not guests respect the strangers in close proximity to them," John Morrey, vice president and general manager of, said in a statement. "The same is true for flying, or for driving. A modicum of consideration for your fellow travelers can go a very long way and may ultimately enhance your overall travel experience."
