For $14 you have to try it at least once. But only if you're in to roller coasters obviously. My wife and daughter tried it and they loved it.
Not to mention the fact everyone I heard exiting the ride couldn't stop talking about how AWESOME and FUN it was.
The line moved quickly, the price was right and its Vegas. You're going to spend the money on either gambling or alcohol so why not a roller coaster.
DO IT!!!
