We used Peninsula Tour to bus our wedding guests between the parking lot and our wedding venue, and then later to bus our guests from the venue to a Bart station. Overall, we were highly pleased! Their prices were by orders of magnitude less expensive than the competitors, and the vehicles were clean and great and on time. That being said, the booking process was a bit chaotic (I had to ask to get an actual contract), and our driver was confused as to what he was supposed to do when he arrived on-site (our other charter company straightened him out). Overall, though, it was an incredible value and they did a great job -- and didn't even complain when it took an extra 20 minutes to load our (inebriated) guests on the bus at the end of the night. Definitely recommended!
