I'm spending 2 weeks studying Italian in Lucca and want to visit Venice for a weekend-I'm not sure if I should take bus or train to Florence and then fast train from there, or travel through Pisa. I want something that is easy, cost effective and fast. Any ideas much appreciated. Also, I know this is a Tuscany forum but if anyone has suggestions for accommodation in Venice for less than 100 euro, also much appreciated. Cheers.
