meals includedAt the Alta base lodges, (definitely at the Peruvian, and I think at all of the lodges with dorm space) all meals are included in the price (even lunch if you want to come down for it). The dorm guests get the same fancy meals as the folks paying top dollar for regular rooms. You don't need a kitchen.
Sometimes the Peruvian will offer a "guest worker" deal: Three hours of work a day in return for an empty bunk in employee housing or maybe in the dorms, plus employee meals, which are not the same as what the regular guests eat. Lift tickets aren't part of this deal, but it is still pretty good.
