Great way to get around the City to popular tourist spots. I stayed in Old Town and walked from my hotel to the trolley. From there, I rode and hopped off at Coronado, spent some time at the beach and in the shops, then hopped on, rode over to Balboa Park and explored and then rode back to Old Town. Never more than a 20 minute wait for the bus and all drivers were informative and friendly. I only wish I had purchased 2 days instead of one!
