I think a lot of these "incidents" are urban legend. Read through the thread carefully, and notice how everyone who describes FEs as being no good anymore are not describing their own experiences, but rather 2nd hand experiences about what they've "heard". Some of the people who spread these comments aren't even current
DCL cruisers- they've moved on. Notice comments that say things like, "when I cruised DCL", or "I don't do FEs anymore but I've heard it's not what it used to be".
It seems that some of the negativity is related to the fact that most FEs originate from Facebook now, rather than the Dis. There is rumored to be a "control freak" of FEs on FB, but most FEs organized via FB have nothing to do with her, and are independently organized by groups that are created by cruisers of each individual cruise.
I recommend ignoring 2nd hand info, and instead listen to people's actual firsthand experiences with FEs.
