Good value and easy to use. We saved 94-121 per person. This was a good option since we were in San Diego for a week and allowed flexibility in plans due to rain. Since the pass includes 1 safari or 1 zoo, we did both, and paid the 2nd out of pocket. The kids were free at the art museum, and used their last pass slot for Belmont rides. We had vehicles, and used the trolley for 1-day (though it was a 2-day), the 1-day would have cost ~60 and we still saved substantially. The trolley is good for touring and going where it is crowded and hard to park like Coronado.

A great day trip to Santiago! Our tour guide, Cindy, was very attentive and responsible, providing detailed explanations throughout the trip, and she was also witty and humorous.

Reviews: USS Midway, Old Town San Diego City Tour from Los Angeles
Guest User2026-09-12
The itinerary was well-planned, with ample time to visit and enjoy each attraction, preventing the trip from feeling rushed. However, we wished we could have spent more time on the aircraft carrier. Our guide, Daniel Chen, was incredibly kind and attentive throughout the journey, and we are very grateful for his hard work and care. We encountered significant traffic congestion on the return trip, so we are also very grateful for his efforts in getting us back safely. Overall, it was a fantastic experience, and we thoroughly enjoyed the trip.
