You know those mini shampoo and conditioner bottles, tiny soap bars, and boxed shower caps? You might never use them in the hotel because you packed your toiletries in a zip lock bag... but bring them home with you. Next time you have company, set them on the bathroom counter to make your guests feel like they're on vacation.
Last week I picked up a rectangular white tray for $4 at Home Goods. Now my guests know just where to look when they realize they forgot lotion. Simple to do and looks nice on the bathroom counter top.
