We will be in San Diego Feb.6-10. We will probably drive to San Diego from Claremont, CA. My questions are, once we are in SD can we get almost anywhere within the city we want through local bus service? Do they run late at night? Hourly? We only want to go to SD sites, happy hours, dining, museums, markets, zoo, etc. We have no interest in going to the beaches on this trip. We will be staying in a B & B just a little SE of Balboa Park. Any hlelp would be appreciated.
