Booked a water taxi from marco polo airport to our hotel in venice. We were dumped on quay side at piazzo san marco because we would not pay driver cash to complete journey to hotel. We showed our booking confirmation but were told hoppa had only booked them to take us to the quay side. We then had to walk for 20 minutes to find our hotel and my wife has a bad knee so this was not good. Many phone calls over weekend and every excuse under the sun why we were not taken to our hotel. If i had not contacted the water taxi firm direct we would not have been picked up and would have missed our flight home. Complained when home but service was dreadfull these people just do not care about customers. Take my advice and book a water taxi through your hotel it costs no more and you will defibately get there
