We are looking at going to Peru in October for 10-11 days. We have talked to friends who have gone and we have narrowed down where we would like to go, but know we need to narrow it down further. We need your help! On our list: Lima, Cusco, Lake Titicaca, Sacred Valley, Machu Picchu and Arequipa. Not in any particular order. We are very active, but like to remember it is our vacation. We have seen several different itineraries, but none seem to fit what we have in mind. We are trying to figure out what we can realistically see? How do we travel with the luggage? Any thoughts or suggestions would be appreciated!
