If you have kids the will love this place. You can walk underwater and there will be sharks swimming over you. If you bring a camera make sure you have a fast lens because it gets abut dark in there. At the end you can touch stingrays and other sea creatures. My wife touched an anemone and it stuck to her finger. This is a fun place and worth the money. You can buy a city pass in San Francisco and for 60 dollars you get access to the museum, trolley rides, a boat trip that takes you under the Golden Gate Bridge plus much more. The city pass is good for a week. We bought them for our whole family and had a blast going to all the museums and other things that were included. We loved our vacation to San Fran and are planning another trip next year!
