I think we chased people off our ''tagged chairs'' about 3 times last trip--2 week period. There are those who don't know and those who don't care. We now put clips and wraps on our chairs even if we don't leave towels so ''something'' is there to hold our guest chairs. Nearly any item on a chair will warn people off if they are paying attention and choose to be observant. BTW the NO PHOTO signs have cut down greatly on camera-use, so signs work.
