I'm appalled. TDO never ceases to surprise me.
To shut down the ride just because the waterfall isn't working seems pretty foolish. Think of it this way, no matter what it's not going to work. If they close the ride, it won't be on and guests will have their dreams of riding Splash crushed. Two losses there. But if they can still run the ride and still make some people happy while waiting for repairs, I think that's the better choice.
I can understand why some of you don't like this, but the fact is that machines break. It's only when they don't get fixed for months and months that we should start blaming TDO. Sometimes you have to pick your battles.
