If you’ve ever stayed in a multi-person hostel dorm room, then you know how important good manners are. Having a bad hostel roommate can literally ruin part of your trip, causing you lack of sleep due to any number of environmental factors. Of course, sleeping in a room with 7 or 9 other people, it’s impossible to have a perfect night’s sleep, but hostel dorm rooms can also be havens of generally bad behavior.

Read on to find out if you’re guilty of any of the following hostel no-nos.

Crinkling plastic bags. Oh my word. If I had a dime for every time someone woke me up by crinkling a plastic bag in a dorm room, I would probably be rich. Using plastic grocery bags seems to be a favorite among backpackers – probably as a money-saving technique – but crinkling plastic bags at 3 am when you are about to depart to catch your early morning train is bad behavior. Either step outside to dig around for your deodorant stick or get it out the night before!

Strewing your stuff. Figuring out where to put all your stuff in a hostel dorm ain’t easy, I know. But strewing it around the entire room as if it were your private hotel is not the way to go. General common courtesy stipulates that you should use half the space under the bottom bed for your rucksack, plus part of your own bed for hanging things. Strew as much stuff as you want on TOP of your own bed, but keep it to that.

Turning the lights on. I’m not sure when exactly the lights go off in most hostels, because most hostels don’t have specific “lights out” rules. However, the basic idea is – if it’s past 10 pm and you open the door to a dark room and there is someone asleep in your dorm, don’t turn the lights on! Most hostels now equip each bed with its own reading light. If you must – use that.

Getting jiggy. Do I need to say much more?

Dressing/undressing. Hostels have bathrooms. Use them. If you are a pro at getting dressed or undressed under the covers, then by all means, have at it. But if you can’t pull your pants up or de-bra yourself without flashing everybody, please get naked in the privacy of a bathroom stall.

Hanging your towel on a stranger’s bed. A lot of backpackers hang their towels to dry at the end of the bed, and that’s fine, so long as it’s your bed. Don’t assume that, just because the people in the next bunk over haven’t used the space at the end of their beds for drying, that it’s fair game. It all comes down to keeping your stuff to your own space.

Being a bad drunk. Yep, I’ve “slept” through a drunken crazed lunatic blubbering and vomiting all night in the room. Not an experience I care to re-live and not one that you should re-enact. Simple rule: don’t get so drunk that you’re going to get sick, and if you do have to get sick, get to the toilets first, please!

Moving other people’s stuff. This one seems pretty clear, but you’d be surprised how many times I’ve come back to my bed, only to find a shirt moved or a pair of shoes shoved under the bed. Luckily, a lot of hostels are starting to install lockers in each room, so you have a place to stow your stuff. But if you don’t check in to a place that has them, don’t touch other people’s stuff, even if they have violated one of the rules above. Wait ’till they come in and ask them to move their stuff.

Stealing. Do I need to explain any further? Don’t be a jerk.

Having stinky shoes. Okay, I realize that some people have a foot condition that they can’t control, and I am not trying to hound on you for your physical ailments. But it doesn’t take much effort to be aware of your smelly foot problem and consider leaving your stinky shoes outside the door of the dorm room, rather than letting them reek up the air inside where everyone is sleeping.

Snoring. This is another ailment that, for many people, can’t be helped. And gentle snoring is something that many people in a hostel dorm can ignore, but if you are a one of those goose honkers (and you know who you are), really… consider getting a private room – for everyone else’s sake. ‘Cause that’s just not fair.
