I'm sure there are others, but off the top of my head I would recommend (those without children) skip Universe of Energy. We like Ellen and tried REALLY hard to like it...but didn't. It is however good for a mid-day nap, especially when it's hot outside.
I have to agree. That's an attraction we ride only once every few years. Once you've done it, there's no reason to do it again, really.
