You could always just show up and walk around the outside of the campus, take a picture of the colorful Google bikes and the Android mascots for the various releases. There are usually lots of Google employees getting some sunlight in the surrounding park. I'm not sure what you'd see inside the buildings. I worked as a consultant for the previous owner, Silicon Graphics/SGI, during the first dot-com boom, and they were neat architecture, but still just office buildings. I think if you plan a whole trip out to Silicon Valley for the atmosphere, you might be kind of disappointed.
