For lunch, we ate by the water on Harbor Island. I had tons of lobster and found the staff to be very nice.
We then walked to Old Town along San Diego Bay. We saw visited one part that housed psychiatric ward across the street from Dirt Cheap Rental Cars and a liquor store.
Old Town had cool old buildings, but was so ridiculously touristy. It was catered to families. We didn't stay long.
We charged Candace's wheelchair in a Starbucks and had a nice long walk back to the hotel.
