Sorry, but I think you're crazy to pass up the opportunity.

At the end of the day, it's the chance to get a quick thrill fix for around the same money as a DW admission (less if you can get a promotional deal).
You should definitely go to Alcatraz though, awesome place. And the Chinatown is one of the best I've been to in the US.
Be sure to wear some flowers in your hair and don't leave your heart there.
EDIT: Sorry, had to add the last sentence, couldn't resist
