We are flying in from Cusco, arriving in Lima at 1:15 in the afternoon on a Sunday. Our departing international flight check-in is 8:30 PM. Is there a secure place to store our luggage at the airport? We were thinking of either hiring a driver/guide for a mini-Lima tour or going by taxi to the Larco Museum & a restaurant. It has occurred to me that the American Airlines counter may not be open when we arrive at 1:15 PM and I'm not sure how to handle our luggage! Ideas?
