How to ski in Portillo
It made me 
"Outstanding! I wanna go there every year!"
How I did it: I booked at www.skiportillo.com. Then I went to Santiago, spend one night in a hostel (very nice, btw) and went to Portillo, which is really close to there.
Resources: Buy ski pants in Santiago (a mall close to the way to Valle Nevado) and rent all equipments in a store close to this mall.
