This is NOT a good sign- at all. Somebody has seen something bad, and it's scared them.
Parks don't close up early- it's just not done as a habit, as it (As we've seen) pissed off every person around and in the end, it doesn't make MONEY. When you're looking at a capital expenditure for rides, and you're not bringing in MONEY, then it's a moot point. The most perishable item in a Theme Park (and in all other industries) is TIME. When you give up a day's worth or potential revenue, you're letting that time go to waste- no income for you to work with.
I have to -seriously- question the Park's management decision on this- It might not be as full during the weekends as you'd like, but it's still better than to have rides, shows and attractions sitting dormant on a perfectly good revenue day. It's either that, or they are sending a signal that IB is having financial difficulties that we're not being exposed to.
I'd bet it's the latter, in which get your charge cards out, folks. I know I'd be looking for a great backyard coaster, cheap. (JetStar, anyone?)
