I've seen the same thing at many parks that open midweek in the off season.
He frequently doesn't.
The point about the attendance is that it increased on the prior year - by more than the amount you saw in the park no less.
I'm quite sure someone said recently 'a water park is not a theme park'. It makes less sense to open it in winter. you're competing with a small enough crowd as it is. Dry park on the other hand, if you're open, you're forcing customers to choose between you and a competitor. If you close, you're giving the game away.
As for the insurance payout, i'm sure it was absorbed into the capex for rivertown, so in a way, they did rebuild it - just elsewhere. (and even if it didn't technically get absorbed into the rivertown budget, it's all CE's money so it really doesn't matter. they got paid by insurance to rebuild vintage cars, and they rebuild vintage cars. end of.
First of all, they're not sacked. Let's not start using emotive and inflammatory language to get people upset about a normal thing that happens every year. They're hired on contracts and the contracts have a fixed end date.
As I understand it Raging Waters in Sydney has a similar issue with retaining staff over seasons, but its just the nature of a seasonal business and the workers go into that eyes open. I think more than a few waterpark folk double as Ski Resort workers in the winter, and many come back year on year.
But that isn't a good enough reason to open the waterpark in winter. It is however a good enough reason to keep your dry park open.
