If you want to experience San Diego, jump on the Hop on Hop off Trolley. The drivers are so much fun and talk about history and fun things to do in the city. They have 9-10 locations you can get on and off. You just have to pay attention to the time as they pick up and drop off every 20-30 minutes at each stop. Itās a great way to enjoy your day. Itās about 40 dollars a person, but weāll worth it.
