The cost of a roundtrip for my family from Rome to Venice is about $200 more riding 2nd class Eurostar vs. IC. IC also takes about 1 hour longer each way. Any thoughts? It appears on Trenitalia that IC goes to the Mestre, but the Eurostar goes to Santa Lucia (I think a closer, preferable train station - but I've never been there). Is it a big deal/time/expense to get from Mestre to Venice, thus adding more time and money? We're trying to economize and $200 is quite a bit of money, but not sure if I don't even know about significant IC down sides.
