We just returned from 2 weeks in Italy, starting with arriving at the Marco Polo Airpot on the Venice mainland. Thanks to a very nice student who posted on TripAdvisor, we were able to save a lot of money on the very first day. We arrived at the airport, went to the little info desk (the one on the right)as you start to exit the airpot, purchased two tickets for the number 15 city bus (Euro 1.00 per person) and took it to the Venzia Mestre Ferrovia (Railway Station on the mainland). It took about 20 minutes but was a very nice ride. We got off the bus there, bought two tickets for the train going to the Santa Lucia Ferroviaria (Railway Station on the Venice island) which was about 2 Euro each. We arrived on the island and walked 15 minutes to our hotel. By looking up the directions on Google Maps for the train station on the island (Fondamenta S. Lucia - 30100 Venice) and our hotel address, we were able to print out a map and step by step instructions for walking there. We saved over 100 Euros by doing this instead of taking a water bus or water taxi which both cost considerably more. You can use that money to take a nice gondola ride if you wish, or help pay for your expensive hotel like we did!
