I was there yesterday and it was cycling non-stop all day half-filled with dummies (the water kind as opposed to the general public kind). My guess is that it'll be open in the coming days. Apocalypse and Crazanity were down, but everything else was running. The park was quiet, but most rides were single-train ops.
Be warned that the parking lot is a bit of a mess right now, but the new solar system thing they're installing seems quite impressive. It provides a ton of shade, and I'd be curious to see the numbers that thing generates.
