Mist sprayers actually make more humidity, which in turns makes things feel hotter i.e. Heat Index (Combination of the Air Temp and Humidity) So the misters that are already in the park would in turn make things hotter.
Personally the Batman queue needs the Air Condtioning on every day above 75 degrees, Because with 100+ people in there it gets very very hot and you can actually get light headed in there.
As for Fans, i really dont see it doing much in the way of cooling off a queue, Think of it this way:
Fans blowing hot air on hot people makes hot air circulation

which doesnt cool you off but make you hotter, Think about it this way, its like trying to run your cars air conditioning the second you start up your car, of course your going to get hot air blowing through there.
For the TV, idea honestly the Lonney Tunes Cartoons are only a few second parts of the classics, not the whole cartoon

The TV's would be an awesome idea if used the right way.
Example: Current Wait Time from This Point, Six Flags History, Looney Tunes Cartoons. ETC etc.
