What’s the best way to travel in Italy during Christmas?

I am planning my vacation to Italy between 12/24-12/31. Just found out train schedule will be very limited around that time, and not available to review now. I can’t cancel or change my air tickets. What’s best way to travel from Rome to Florence (12/26) to Venice (12/28) to Milan (12/29)? Please share and help. Thank a lot.
