Either it's being done to save on cost or...
Maintenance. Yes, 6 hours a week isn't going to put a dent in the ride's problems, but it COULD mean that Splash isn't getting a refurb again in 2013 and they're trying to do anything they can to allow it to limp to its next refurb. If JC is getting a substantial refurb next year, whether it's extended or just plussed as is, they might not take Splash down as well. Just a thought.
