Anyone ever stayed in the dorms there?
Don't know about the dorm, but I've heard good things about the Snowpine!
I have stayed in the Peruvian's a few times. The overflow dorm at the Peruvian is extremely small for 4 people and I wouldn't recommend it unless your young and very intoxicated! The main dorm is larger, but I'm getting a little old for sharing?
Sometimes if you're arriving late and missing the meals, the "bunkers" w/o windows, in the Cliff can be cheaper?
