I need to plan a vacation for the wife and I. We did China a few years ago, and then big sites in Europe over the last three years. Now I need a vacation for 4-7 days to plug in over Christmas. We really want to do Peru and the Inca Trail, but that's gonna have to wait until the spring when we have 10 days. Give me tips...I want decent weather (why be too cold or too hot), and somewhere that I can see things and do stuff (like ride bikes).
