I think it's lovely that you want to provide nice soaps and shampoos.
Do you remember the little b&b I stayed in that offered shampoos and soaps that were all random samples and things from other hotels? Most half used. Soggy soap in the shower stall. That place is still in business. The real, old fashioned 'you can stay in a room in my home for the night' kind of b&b. Empty pizza boxes on the porch when you come in. You can join the folks in their living room and watch what's on the tv. Personal clothes in the closet and bureaus. Grammy's hair curlers and old fashioned bonnet hair dryer on the night stand. And a jack and jill bathroom. LOL Her place was an air bnb long before air existed. Nice lady..
