A little bit of advice (piggybacking on what PamNC said) - Never listen to transportation CMs (ie. monorail workers, ferryboat operators, Friendship barges, tram drivers). They are notorious for giving out phony info. As for other CMs, be sure to take what they say with a grain of salt, too.
Nevertheless, it's always fun.
BTW, the monorail expansion would be TREMENDOUSLY expensive and probably won't ever happen. With the multitude of resorts now, there's no way they could connect the monorail to all of them which means they'd probably have to make another hub like the TTC...but then what would be the point of that?
Then again, these rumors are always fun!
