If you feel your hotel rooms never have enough hangers but you don’t want to schlep the big, bulky ones from home, check out the array of inflatable hangers on Amazon. You can buy them for cheap ($2.50 and up) and they hardly take any space in your bag.
Inflatable hangers are great for drying shirts, too, as the front and back of the shirt are kept apart from each other and air can circulate better for drying. I had several of these 35 years ago, but have not seen any recently. Glad to know that the product has made a come-back.
