This was our first visit to San Diego and we took advantage of this hop on hop off tour to get oriented. We booked a two day ticket and on the first day we did the full circuit, except for a a short stop in Coronado, which was excellent and a stop at Balboa Park to get a feel for the place.
The second day we stopped of at the first stop and did the USS Midway and the North bay trip(you can get discount if you book via the bus trip company).
This is a great way to get to know the area. We were based up on Mission Beach and it took us a $10 round trip ticket on the No8 bus down to Old Town to catch the tour but it was well worth it.
The bus tour drivers were helpful and very informative as were the staff at the Old Town deport.
All in all, a great way to get to know the area.
