Trying to decide the difference between these two trips for early '26?? Besides the one extra day, different hotels and $6K difference, I don't see any difference. What am I missing? They both have the same activity and pace, and both visit Machu Picchu. Are the hotels really that much nicer?? Maybe it's the ship? We are 68 years young, and used to traveling difficult trips, KT Safari, Antarctica... (New hips and new knees!!) We are more than willing to pay the extra of luxury it indeed, but is it that significant?
