Has anyone done a mid- or post/pre cruise which includes a side trip to Machu Picchu? I'm looking at a couple of cruises (Sapphire Princess, for one) that include flights directly into Cusco, at 11,000 feet, and tours of the city that begin right after getting off the airplane. I'm wondering how this all works out with a bunch of geezers.
I have gone to Machu Picchu before, but I booked my own tours, and, on the advice of other travelers, immediately made a descent into the Sacred Valley - 9,000 feet - to avoid the lower oxygen levels of Cusco. I remember stepping off the plane and first thinking: geez, I hope I can make it to the shuttle van! I wasn't the only one; my 14 y/o daughter was with me and she felt the same. Once inside the shuttle van we each leaned back our seats to relieve the dizziness. I cannot imagine doing a walking tour of Cusco within hours of leaving the ship, at sea level.
Anyone who can share their experience?
