Visit Mendoza, Argentina. Add it to your bucket list. It is a beautiful destination in South America tucked in the foothills of the Andes with sprawling vineyards, affordable prices, amazing people, insane views and delicious food and wine.
Lima, Peru is a city not to be missed. Many will visit either before or after Cuzco (since Lima is the city most international travelers fly in and out of when visiting Peru). We came straight from Cuzco and I was incredibly sick from the altitude. What I needed in Lima was relaxation and rejuvenation. We stayed at Casa Andina Premium in Miraflores and it was exactly what we needed.
