As part of our trip, my family will be traveling from Innsbruck to Venice by train. On the rail Europe website I am able to make a reservation from Verona to Venice. But not able to make one at all from Innsbruck to Verona. Does the Innsbruck train go to Verona, then change trains to Venice - that's what I'm assuming. Is a reservation recommended for any part of the trip? If so can they be done at the station or should be purchased before the trip? Has anyone else done this trip? Is all luggage kept with you or do you check the large suitcases like on a plane? Thanks.
