^That is once again not necessarily true. There was a webcam that faced that direction for the Hurricane Harbor construction back in 2005, but there hasn't been a webcam since then for construction.
Sometimes parks do it, sometimes not. But currently there is no webcam.

It would be helpful to see the crowds and lines for the rides if it is a 90+minute wait vs 25min for RB. For now I just use Ride Hopper for iPhone. It does the job pretty well.
I would guess you can see where the line ends. For example, Raging Bull, you would see if the first section is full or half empty or if the line goes to the second section can depend on how long it would take until you get into the station. Also, how many trains running can make a difference as well.
