We purposely left the Do Not Disturb sign on the door every day as we did not want any housekeeping done. When we returned on Friday, our room had been picked up and towels added, which was fine, but an ash tray was also added to our balcony (we do not smoke and it was not there wed or Thurs because we sat outside. The ash tray had ashes and a small piece of foil in it. Someone came into our room, dis soms cleaning, then smoked and/or dis drugs on our balcony while we were out.
