I visited recently. It's way too popular at the moment. They have an army of private security personnel on site, definitely for daylight hours on weekends. They are observing all the obvious ways in. They detected me when I was lurking next to a ride in the woods. I did eventually find a viable way to reach the biggest roller coaster. I think they have 24 hour security of some sort too, since we had to take evasive action at 7am on Sunday morning. My view is that it's best left for a while now and it stands a chance of being a lot better once the heat has gone from the site.
