I love the idea of closing nile down and having it become its own haunted house. However I see a few problems. #1 the trough of nile is not flat, it has "logs" that dot the bottom, that create the waves. That would be a huge tripping hazard in the dark unless they were covered up. You obviously couldn't use the entire nile, as towards the end it gets VERY deep, would the park build a staircase to get into the trough and out of it? They could as they did the same thing with the Express tunnel, but that is a closed ride and the staircase is permenant. Nile will need to operate atleast up until Halloweekends.
Otherwise, even as one of the most vocal people out there, I wouldn't have any problems with them closing down nile entirely during Halloweekends. Its a water ride. I think its a great idea.
