Hi @Eileen462,
I have all of the above.
Wood floors throughout 1st level common areas (livingroom, kitchen, dining room) and the staircase which leads to the 2nd level.
Tile in all bathrooms & laundry.
Carpet in bedrooms only.
I have a small sign at the entrance and at the base of the staircase that reads "No shoes please".
Most guests are respectful.
I can tell when guests ignore the signs...the carpet at the bedroom doorways clearly show their dirty shoe-prints. It's not permanent damage but makes me appreciate the wood floors.
In all these years of hosting I had only one group of guests who obviously rolled a large wheeled-ice-chest (filled to capacity with canned beverages & ice, I'm sure) leaving visible wheel gouges in the wood floor, from the entry doorway, through the livingroom, and directly to the slider door which opens out onto the back deck. Sigh.
I don't understand why they didn't simply roll it from the driveway to the back deck in the first place!! They managed to tear the front door's screen door by wrestling the ice-chest into the doorway too.
We were able to sand and polish the floor to repair it and replace the door screen, so it wasn't the end of the world, just annoying having to deal with such carelessness.
After all if that I remain a fan of wood floors.
