I'm also in California. I have a few suggestions if anyone wants. There is Six Flags, Marine World, San Francisco has a lot (I've never been there so forgive me if you have) L.A has some stuff, Santa Cruz has the beaches and Boardwalk (if we go in August, it would probably be a lot cheaper than any other place). Santa Cruz is probably the most likely option in my case, I also have camp in the beginning of August but I should be able to come before or after camp.
