We did the most amazing tour of the city on the hop on hop off Trolley day pass tour. The driver/tour guide was SO VERY knowleable on the history of San Diego not to mention polite and friendly. The tour included....the harbour, seaport village, horton plaza, Coronado Island, San Diego zoo, Balboa park. Each of these attractions were equally interesting. I would recommend this tour to everybody who visits San Diego. Our tour drivers on the day were Hatch & Bill...... and they did an excellent job.
