Not necessarily....You can post on the cast portal, the cast paper, and on the bulletin boards, but unless it is actually READ...it is useless. They put out a CM guide to EVERYTHING going on all week at the reorts, times, locations, hours etc., But if the cm does not GET one, which is their responsibility, then its useless. Like I posted before, Management used to tell us stuff all the time, most times it was pure gossip.
Another thing, if you are looking for specific merchandise, ask more than one CM. Sometimes the CM does not take the time to learn new merchandise, or could care less....Most of them will ask, or look for something, but general character merch questions do not get a thorough answer.
