i went to portillo 2 summers ago and it was hella tight. a small resort, but it was skiing in august so i couldn't bitch. the people there are really nice, and the food that was included was sooooo fucking good. i put them as #1 for resort food. i dont know how much tickets are anymore but im sure u can find it on their website http://www.skiportillo.com/home-eng.html
i want to go to las lenas sometime in the future b/c its sooo much bigger than portillo.
