The Marriott Marque & Marina and Marriott Gas Lamp are both closer to the Zoo (Balboa Park) and the airport. Night time driving in a strange city can be tricky. My wife and I would not have a problem walking to the Zoo from the Marque or Gas Lamp, but we like to walk. (The Zoo is 3.5 miles from the Marque.) There will probably be more to do downtown around the Marque.
