Never liked water rides really (having to drive home for 3 hours feeling soggy is never a fun thing to do
) but I agree that the Flume is looking like a VERY tired ride now. It's lasted longer than Corkscrew did though which is saying something.
Alton Towers does need a new water ride really, even if it isn't on the same scale as The Flume. I know Aquatrax has been batted around a lot in discussion before, but how? If money was no object, I'd be happy to build a water coaster entirely over that lake.
