Thanks for the input. We will be spending time in Cuzco, the Sacred Valley and Puerto Maldonado. I have heard of Colca Canyon. So many places to visit. Not sure if I will make it back to South America. We try to do one big trip a year and have a lot on our bucket list. A small trip I am excited about is going back and renting a European Canal boat and spending 4 nights on the Erie Canal. My brother and I boated the Hudson from Manhattan to Lake Champlain a few years back and if you have never been through the locks, it is very fun.
