There are many places in San Diego to visit and you are able to park your car and either catch a trolley or a bus for pretty cheap. If you stay in Mission Valley, there is plenty of shopping including two malls within 2 miles of each other. There is also tons of places to eat such as Dave and Busters, In and Out, Gordon Biersh (local brewery), Bennyhana's, ect. Another place to visit while there is Old Towne. Very neat place. A couple other areas that might interest you if visiting San Diego, Coronado. This is where the Hotel Del Coronado is located. There are plenty of places to grab a bite to eat on the island and if you want to take a water taxi from downtown to the island, that is one way to enjoy your visit.
