Extremely easy and most people combine the Galapagos cruise with Machu Picchu.

I will use Silver Galapagos it is now getting rave reviews and Silversea offers a trip to Machu Picchu.

If I do this and there are enough who want to go to Machu PIcchu I may set up a private tour through Ker & Downey and spend a couple of nights in the Sacred Valley. A neat place and a shame to miss when you go this far, plus a way to adjust to the climate as it is the lowest elevation. If we do that Ken and I will go of course.

Ballpark elevations

Sacred Valley - 8000 feet
Machu Picchu - 9000 feet
Cusco - 11,200 feet

Should know for sure next week if this is going to happen.
