I have learned from experience that it is cruel to both guests and home owners to hide the extra toilet paper and room deodorizer. Like the book says, Everybody Poops. So you'd better deal with it!
Put two extra rolls in a pretty basket on the back of the toilet and your guests will never have to ransack your cabinets with their pants around their ankles.
Keep the visit pleasant by having room spray in the bathroom available and obvious. Many companies make some pretty ones. Try Method's Aroma Spray or something from Bath and Body Works. Even old perfume will work.
You are welcome.
