It is definitely worth a visit once things get back to normal politically. Lima is a lovely city for business and food but the beaches were rocky for my tastes. I wouldn't spend more than a night there getting to other destinations like Cusco (at least 3 days; I enjoyed shopping for souvenirs in the local malls that are just a collection of independent stands) and Arequipa (at least 2 days). There was a 1-day bus tour I liked out of Lima that went to Ica (sea lions and sea birds), Huacachina (dune buggies), and a winery. The same company also did 1-day tours of Vinicunca from Cusco. Consider flights for routes through the mountains that are difficult to drive through.
