The description of this tour is incorrect as we thought we were walking around other parts of Venice but it is just a 2 hour tour of the Doges Palace. The tour guide was excellent but having paid online with Viator we did not realise we had to also pay for the entrance fee into the Doges Palace which was €13 each, the same as we would have paid on the door if we had done it ourselves. I am not sure therefore why we had to pay Viator £20 each before we went. Overall it was not worth the jump the line fee which I'm assuming the £20 each was for as there was no queue anyway and we could have had our own pre - recorded guide from the Palace.
Very disappointing with 6 Gondolas going out together with only one having the serenade on it. The meal was average and as it was only 2 courses included, having paid for desserts, drinks and coffee on top it cost us another €46 so all in all a very expensive meal. The restaurant is also very difficult to find so if you do go find it first before you go on the Gondola.
