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
