I'm not sure about Madonna, but I know the bus station in Trento is very
good, with buses going to various resorts. Many years ago I did a week in
Soll, followed by a week in Andalo. I got the train from Insbruck through
the what do you call it pass, down to Trento. The snow in the pass was
unbelievable, and the scenery fantastic. I stayed in Trento overnight, but
that was my prefarence.
Good Luck
