How do you pack your dirty clothing when moving from hotel to hotel?

This might seem obvious to some, and completely out of the question to others, but it's what I do:

Wash your laundry before going to a new hotel.

I do it in the hotel sink at night before going to bed, and by morning my clothes are usually completely dry. Of course, this can depend a lot on your clothing, and the material from which they are made. I make a point to travel with quick-drying clothes, and a travel clothes line to make this task easier.

Traveling this way also makes it easier to travel lighter, as you can carry fewer items of clothing, as you can always do laundry on demand, rather than waiting until the end of your journey, or when laundry facilities are available.

I take a very large clear plastic bag (sold I believe as a leaf bag, or paper recycling bag) that is larger than a "green garbage bag" and I use it as a laundry bag. I typically leave it in the suitcase, unpack my clean clothes, and put dirty clothes into it after I wear them, like a hamper. When it's time to go, I can fold and compress the dirty clothes if I need to, then layer the non-clothes items (bathroom stuff, books I've read, etc) on top and then clean clothes on top of that. For most of my trips, by the time I head home there are little or no clean clothes remaining so the dirty clothes need 80% of the suitcase.

When I get home I can just dump the laundry bag as part of doing the laundry, and then I put the bag back in my suitcase for next time. I've been using the same bag for years and years, and there are more on the shelf should it ever wear out.

The advantages of being clear: I can see what is in it, no hotel people will think it's a real garbage bag and throw it out for me, customs people can see that it's clothes and might not treat it badly, etc. Because it's plastic it takes less room than a cloth bag, and if something is damp or actively nasty it will protect the rest of my clothes from the mess.

I just use a large plastic garbage bag a.k.a. bin liner. If anything is wet or really dirty or really smelly, then I may double or even triple bag it.

If you're lucky your luggage has more than one compartment. My current backpack has a separate zippable section at the bottom, below the main section. I use this for storing the dirty laundry in its bag(s).

This way I can even add dirty items to the laundry section without having to pull everything out and re-pack if I'm moving before I expect to wash laundry next.

Any clean clothes that I want to keep nice do not go near this bottom laundry section. I'll put rugged stuff like jeans above the laundry section.

I always use an old pillow case for this purpose.

This way I can neatly store all dirty clothing in a single place but avoid the airtight properties of a plastic bag.

First up, what not to do - don't store them in a hotel laundry bag. It might look tempting, as it's a handy plastic bag in your hotel room, but there's a fair risk that you'll come back to your hotel room one day to find a pile of clean clothes and a fair sized bill...

Now, talking of clean clothes - check with the hotel, and think about this when booking. You can sometimes book rates that include a few items of laundry ever day, often as part of a longer stay package with breakfast etc. These can be good value, mean you don't need to take as many things with you in the first place, and you won't have dirty washing to deal with! Some hotels have very reasonable laundry fees, others huge ones, so it can be worth just paying sometimes too. Also, consider checking nearby laundries and dry cleaners on longer trips, that can work out well too. Some (mostly lowerer end) hotels offer free guest laundries, so you just need to buy/bring some laundry powder/liquid and you're done!

Assuming you can't get things washed though, my normal way to deal with it is to go out with an expanding suitcase fairly expanded, including a bag (rucksack, small duffel bag etc) in there. As the trip goes on, the dirty washing goes into the other bag, and the suitcase gets compressed. It does mean you carry bag+suitcase rather than just suitcase, but keeps it all separate. (The expanding suitcase option allows you to keep the suitcase "full", so things don't move around and get creased) When it's time to come home, I'll sometimes just be lazy and check the dirty washing bag along with my suitcase! Otherwise, I decant the dirty washing into a few plastic bags, squish them down, expand out the suitcase, and fully re-pack.

(For very short trips, I tend to just roll the dirty washing up inside a dirty shirt, stuff that into a gap, and know I'll be unpacking at home in a few hours so it's no big deal.)

Ever heard of Canoe Bags ?? Simply, place folded up dirty clothes into one of these bags (perhaps bring two ?? one for lights / one for darks) and squeeze the air out. Then seal.

• no smells
• no wet leaks
• easily packed ready for washing

My method to pack my suitcase is very suitable to deal with this particular problem. What I do in general is to put all the rigid stuff (things like shoes, tripods, chargers etc.) first in the empty suitcase and put them apart a bit. E.g. don't put your running shoes in a single plastic bag, use two bags and put them some distance from each other. Then you put in your clothes. You start with the smallest items like socks and you put them in between the spaces with the aim of getting to an even level. You then fold your clothes such that they fit well into an available area, but not with the aim of being neat.

When your suitcase is filled evenly up to some level, you'll can continue filling it evenly by putting in shirts, trousers, etc. in a largely unfolded way so that it covers most of the area in an even way as much as possible. At every step you just correct for any unevenness, so you end up utilizing the available volume of the suitcase in a very efficient way. If the suitcase would end up being quite full and would require some pressure to close, that pressure will act quite evenly over the entire area, you then don't need to apply a lot of force to compress the contents to close the suitcase.

Then to deal with dirty clothes, all you need to do is decide which ones to put in first. If most clothes are clean, you can choose to put in the clean clothes first as you'll likely reach even level with the clean clothes. You can put in a plastic bag to separate the bottom layer of clean clothes from the top layer of dirty clothes.
