We visited here mostly because Discovery Kingdom in Vallejo doesn't have an aquarium anymore. Its a nice place, price is good, parking is rough if you don't arrive early. I think we got there about ten and had one of the last spots before the parking lot was full. There's a lot more to do than just the aquarium, so be sure to see the other attractions in the building and nearby. Golden Gate Park puts on a show all of its own, and people-watching makes for excellent sport!
