The walking tour was great and very interesting and informative the guide was very knowledgeable. The only disappointing thing was that six of us were jammed into the gondola and we had thought we would enjoy the ride on our own. Very uncomfortable.
Great tour. Our guide was excellent and gave us lots of information about the sights and what to look out for. Going with the group did get us into St. Marco's without queuing and onto the Gondolas very efficiently. The tour didn't feel rushed and you felt you covered a lot over the three hours. Going in the group means you're unlikely to get the romantic Gondola trip, however if you just after the experience its well worth including it in the itinerary. Take a snack/drink with you as you don't really get opportunity to get anything whilst on the tour.
This was a very informative and interesting way to get your feet on the ground in Venice. Although the tour was only three hours long, we covered a lot of ground. The tour guide used a headset that transmitted her narrative to earphones worn by the tour participants, so we could hear her even when large crowds were around. A couple of downsides to be aware of: it appears that all the tour groups congregate at St. Mark's at the same time in the morning, so it's extremely crowded and noisy. Also, th gondola ride was a little uninteresting would have been nice to have had a gondolier who wanted to explain what we were seeing as we moved along. But that was minor, I guess. I can't say enough about our guide, Marie Therese. She was fabulous knowledgable and passionate about the city and imparted lots of little-known and interesting tidbits throughout the tour. Highly recommend her.
