Our family is planning to meet in San Diego for a long weekend in a couple of weeks. There are six adults and three children (all under seven) and we are staying at the Hotel Del Coronado. I need advice on how to get from the airport to the Del and back and also to the zoo. The hotel shuttle only seats five. We could take multiple taxis. We have considered renting a van but don't plan to do a lot of driving. Is the trolley tour a good way to get to and from the zoo? Would welcome any suggestions!
