Wow! I have used the room glasses in the past but NEVER again! I have bought coffee cups for extended stays; now I will be sure to have disposable cups and glasses only (if I don't drink from my own can or bottle - which I do clean before drinking from). I constantly wash my hands for cleanliness but ALWAYS assumed that the glasses and cups in the rooms were cleaned - this was an eye opener! I do check the sheets and don't sit on the bedspreads nor walk barefoot on the carpets. I always use a clean towel on the bathroom floors; now I guess I wasn't being out of line. I've traveled a lot and haven't gotten sick yet - guess I've been lucky - happy travels!
