My family and I went on the trolley tour. We bought a one day ticket. I would recommend a multiple day pass, use it to get around the town, get off and see the museums, explore the sites.
I enjoyed the first part of the tour (JACK) was great, I enjoyed his comments, stories and his overall demeanor. He makes everyone feel confortable by asking you where you are from (state) and then "introducing " everyone one the tour, gave some lite teasing to certain people 😉. We got off the trophy at the Del Coronado Hotel, the second trolky wasn't as fun or entertaining, we wished we had stayed with Jack.
Over all this is a great way to see the city, great way to get around and see the history if San diego.
