Traveling to Qinghai, one hotel a day, what can I do with washing clothes?

Look at the weather and hotel layout. Last week, I traveled for a week, five days and four nights and changed to four hotels. Two of them have balconies, so it's no problem to hang clothes and the weather is good. All the clothes are ready before checking out. Two others have no balcony and can only be hung indoors. First, they dry the water in the bathroom, and then they take them to the closet or other places in the room to hang clothes. The air conditioner was turned on, and then they blew it with a fan before checking out and hung it in the next hotel.
