Absolutely brilliant. If you go to Venice, you just have to go on the gondolas, and this tour was magical. We booked the 7.30 tour, which was great as it was very light when we set off from the jetty, but by the time we reached the Grand Canal the sun was setting - just magical.
The bus tour was good. The Eiffel Tower tour and lunch were very good - albeit the food was 'Coles Cafeteria' style,arriving in plastic containers! The canal trip was horrendous though - the large boat with hundreds of people,including children, made it difficult to hear the tour guide and to see any of the attractions - especially if you weren't lucky enough to get a seat on the side of the boat. The only plus about the whole tour was not having to wait in line to get up the Eiffel Tower.
