We will be going on the Rick Steves' "Best of Italy in 17 Days" tour this coming April. Our tour begins on April 12 in Varenna. We will be staying in Milan for a couple of days prior to the tour. We wish to travel by train from Milan to Varenna late morning on Thursday, April 11.
For anyone who is familiar with this train, can you answer a few questions:
Are advance reservations necessary, or are seats plentiful so that tickets can be purchased the morning of travel? We don't want to risk missing this train as we need to be in Varenna the following day for the beginning of our tour.
Can we make reservations in advance? If so, do you know the web address?
How frequently does this train run? Approximate cost of tickets?
Any other advice or information would be most appreciated.
