They roll out the red carpet in prime location, and then get mad when passengers step on it to take their own pictures. The look on the photographer's face last year near Hubbard Glacier (on Jewel) was scary. What kind of picture could you even get if they're taking your picture on a narrow red carpet with crowds of people on the sides?
Also, much less crowded on lower decks. On the Jewel I had the promenade deck practically all to myself. So much less stressful.
