That's a bummer about the lounges. Are there any in the domestic terminal? I should have access or would be willing to pay. Otherwise what would you suggest about sleeping? Find an airport hotel or is the airport good for sleeping? We're on the 6 am flight to Cusco so we're talking about 4-5 hours.

Will have to consider the Lima daytrip vs. spending a night. I personally like cities and we'll have about 4 days in Cusco in addition to the 4 day trail trek so I thought it might be nice to do a Monday night and Tuesday in Lima to get some city time. But vacation is great no matter where it is
