There is a knack to packing. I can’t claim that I have fully mastered it and still tend to overpack, but I generally try to take a more minimal approach these days.
Pack less and be prepared to do some washing, especially if you are in one location for a few days
In the US in particular, budget hotels tend to have self-service laundries (worth checking when you book if you need to get some laundry done), where you can get a load washed and tumble dried for a few dollars. More upmarket hotels tend to have laundry services, which are extortionate.
Carry some detergent with you, which you can use in a laundry, or just in the bath / sink at a pinch. I carry laundry detergent sheets as these take up very little space and are flat (Dr. Beckmann Magic Leaves seem to do the job)
I have been known to carry a portable washing line and pegs but have never used them as there are usually other options for drying (even if it is balcony, warm back seat of the car etc.)
