We have never had any trouble with them in our home, but I agree with the PP that I probably would not take a chance. You don't want to be stuck with a damage charge just to have a decoration on the wall.
We keep suction cup hooks in our OL to use in the villa bathroom for hanging washcloths and wet swimwear. You can find them at most hardware stores (especially this time of year). We plan on putting one on a smooth surface to hold our son's stocking. We will probably put it on the sliding glass door or mirror in the room. We'll figure it out when we get there (in 9 days!

).
Enjoy your trip!
