As of September 2012, they were doing a double feature - Journey to the Center of the Earth followed by some bamboo roller coaster simulation. The Journey to the Center of the Earth was by FAR the better of the two, of course, with scenes straight from the movie. You're strapped into one of those "moving rows of seats" things which tip and tilt and jolt back and forth and up and down. Water mist is sprayed in your face, too, from time to time, but not enough to actually get you wet. The bamboo roller coaster was a little...odd. Definitely a macabre sense of humor with rats and bugs and all sorts of unfriendly animals who almost get run over by the "roller coaster".
Not bad for the price, and if you go on a week day during the off-season, you may just get the entire ride to yourself (like we did!)
