We learned that when you use a hop on hop off type of service, to stay on and see it all then decide where you want to visit longer. Service was fantastic and the drivers had a lot of good info. Most all knew the area well and did a great job. The picture is the waterfront, and you can actually walk between the 2 points. We bought tickets for two days, so a little Uber or Lyft ride back once we stayed later at night, made for a great trip. Viator could use a little training, we called and they could not really answer the questions that I asked about using it. This company is not the same one as in San Francisco, and they are much better here (San Diego). We really enjoyed the ride, coming every 20 minutes or sooner. Easy to do. Wish Viator could have mailed us a map once booking, then it would have answered all of our questions. Would do this again in a heart beat.
