@Alain1308 I've always supplied body wash and never had a problem. It's really good kind that I like. Guest like it also as they use it.
About 6 months ago I included travel size shampoo, conditioner and small bar of soap in a zip lock pouch. Only 2 guest have used them but it's still a nice touch.
Also supply laundry detergent, pump hand soap in bathroom (guest use a lot of this) and same hand soap in kitchen, plus dish soap, lots of TP, paper towels, and cloth dish towels.
I've always thought guest should supply their own tooth brush, tooth paste, etc and so far no complaints.
