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.
