Will be traveling around the central coast in June, 2014 with 17 year old son. I was sure I wanted to visit Monterey Aquarium but after reading some information and reviews, I am not so sure. We have a couple good aquariums here in the East. My question is about San Francisco museums - which one do the destination experts think is better (keeping in mind a 17 year old) - the Exploratorium or the California Academy of Sciences? I'm leaning toward Exploratorium but would love some input. Thanks.
