I'm going to answer this question first. Yes, we do know employees at Google. Currently the only way to get a tour is to know an employee and have them hook you up. We have been on a tour of the Googleplex in the past in Mountain View and the tour and consisted of visiting many buildings on campus. Our tour this time mainly consisted of the Google Visitor's Center at 1191 Landings Drive and the Gift Store. We did get to see the world famous Google bikes, the T-Rex art display and the Android Statues. The Google Campus has a way different vibe than Facebook. Google does feel like a college campus where Facebook feels a little bit like Main Street USA at Disneyland. Both are fun, just different.
