If they're not going to take that dreadful screen down, how about one on the back of the screen, pointed towards MF and the Trail, and another on on top of White Water Landing looking down on Frontier Town towards the Mine Ride/rail crossing, and then another one on the top of the "high" turnaround on the Gemini (Witch's Wheel side) looking towards the Magnum and the Corkscrew? Those three might get you a good feel for the overall crowd in the park, and wouldn't be close enough to "focus" on anybody in particular.
