Planning a trip to Machu Pichu for 2020. Going with a travel company called discoveryxa. We with them to Kenya last summer and had an amazing trip. In addition to Machu Pichu, we will be going to Lake Titicaca, and the Rain Forest. Is there anything worth seeing in Lima for a few days either before our tour or after? We like to add something in the "neighborhood" and have thought of the Galapagos islands or Iguazu Falls. Any thoughts on either of those places or someplace else?
