I am reaching Milan, Italy in 28th February, 2014. I would like to visit Venice from Milan on 3rd March and want to return at Milan on same day evening/night. Can you please suggest me how to go Venice by train. I like to explore Venice in 3-4 hours only. Please suggest what to see and how to visit the places at Venice in such a short time. Please guide me about expenses. I am looking for budget option.
