I wish the guide use the transport/waiting time to explain and talk about the attractions to offset the audio guides a bit. Instead we got really uncomfortable discussions on abortion politics, not really what I'm looking for on a vacation, sorry. I'm very happy I was able to join the tour last minute due to changes in another tour. The operator was very easy to communicate with.”
