Great way to see the top attractions in San Diego all in one day. Great deal especially if you buy the go pass. Rico and Mary Beth were excellent tour guide operators and gave a lot of interesting information and facts. Would definitely use again in another city to get the lay of the land. Would be better if there was some sort of schedule or app so you know when they are coming and leaving the station but they do come every 20 minutes throughout the day so you never have to wait long. Would recommend parking in old town and taking the full day tour.
