If you want a not so cold start, try the Pitztaler Gletscher. You get up
there by underground railway. Same as on the Mölltal.

Any ski run at 3000m (10000 feet) altitude can be cold and windy, so it
might be wise to buy a ticket for, say, 5 days out of seven. On some days
they just can't open the runs due to bad weather.

Enjoy your stay!
