ha! saw that article this AM, and sent to my daughters. this is not our first visit to Rome or the Sistine Chapel. My daughter did a semester in Rome with the University of Dallas her sophomore year, and the younger daughter and i went over the week of Thanksgiving to visit her and we toured the Sistine Chapel then. We were def appalled at the nonstop talking and pic taking despite them telling you in literally every language under the sun NOT TO TALK OR TAKE PIX!
