Our guide was nice enough, but kind of difficult to understand. She walked very quickly, although we had several older people in our group who were struggling to keep up (one couple just left), but then when we got to each site, she would stay there for a long time, even after she finished talking. I’m not sure what she was waiting for. Then we made it back around for the gondola ride which was totally disappointing. The gondolier said nothing. Not one word. Didn’t describe what we were seeing, didn’t talk to us, sing or anything. He just yelled back and forth with his buddies.
