Then 15s definitely don't Chant as much or in as many different places as they did in the "anytime,anywhere Chant" days.I think Disney has cracked down on them, it’s been around 3 yrs since I’ve stayed during prime time tour groups but our last stays at POR and POFQ there were tour groups. They were very well behaved. I was expecting the worst and was pleasantly surprised. On a bus going back to POFQ, tour group was on it going to POR mid day. The group leader really kept them in line, when they started getting too loud. And during a POR stay they were quiet and respectful the places I saw them, at pool & food court.
The introduciton of the Super Greeters has helped tremendously.
But,ask any regular July WDW Guest and they will tell you that they still have their MOMENTS!lol
