The problem with it being publicly known that there has been softs every night in a row since Thursday, I can kind of see where there expectations for this to open to be higher & higher each night. If only they would understand that it has been opening around 6 every night, & once it does open, it will most likely be open till park close & will have plenty of time to ride. But they certainly couldnt get mad at USF, as its not advertized as open, only themselves for taking the chance on waiting with the chance they might not ride.
However, since it has been opening relatively the same time every day now, it would make things easier if they just put out a sign that says "Possibly opening at 6pm" so that people would at least go do other stuff than come back, than that area wouldnt be so congested. They could also come on the mega phone & say "There's no gaurantees, but if we do open tonight, it wont be until 6pm. so please take this time to enjoy the rest of the attractions in the park."
