What I noticed this year was that the security guards where we stay were more protective of the guests than in past years. The minute they perceived that a higgler had "outstayed his/her welcome" they were right there making them move on. Similar thing happened to me at a restaurant at lunch time. My companion had gone back to the hotel to get some money to pay the CD vendor and a young higgler approached me. I don't even remember what he was selling, but I said no thank you. He tried to say something else, and the owner of the restaurant (who was sitting in another area but obviously watching closely) lit into him to leave me alone, I had said no.
