First there was Tripadvisor.com. It was a great forum for travelers to go and share their hotel experiences with one another. Now hoteliers are fighting back. Turns out there are as many “bad guests” as there are bad stays. What gets you blacklisted by a hotel? Well you reverse the room charge on your credit card (i.e. skip out), smoke in your non-smoking room, trash said room or steal things. Those and many more offenses can get you added to the GuestChecker.com database. Just thought you should know.
