Efficient way to see many parts of San Diego. Unfortunately, we started too late i(around noon) to really benefit from the "Hop Off" options since the last pickups were quite early, We had to stay on board through several stops, finally getting off at Old Town and then taking Uber/Lyft back to our hotel in order to have enough time there. I would have liked the buses to run later. The view from Coronado Bridge is spectacular. The drivers/tour guides were wonderful. Shout out to Paul especially.
