Hi Dan-
       You're in a tough predicament because if you don't pay to rent a
car and you still want to get around it's probably going to consume more
money or more of your time.
       I'm only going to comment on San Diego because that's where I
live. Here it's next to impossible to get around without a car because
it's so spread out. The S.D Zoo and Balboa Park are within walking
distance of each other. Sea World is about a 10 min. ride by car west of
the Zoo area. The Wild Animal Park is about 30-40 minutes north of the
city. The rapid transit system here consists of buses and "the trolley"
that provides minimal and time-consuming transportation. If you want to
rely on taxis, you'll have to pay a bit more but you'll save time and
energy. Good luck !
