This was one of the highlights of our trip to San Diego. By doing the hop on/hop off trolley, you can spend as much time at any of the stops as you want. Trolley stops clearly marked and you don’t wait more than 10-15 minutes for pickup, then onto the next destination. Super drivers, great information as you travel the route. This is a great way to see the high points of the city! Would def do again on next visit as we just ran out of time!
