Arriving in Cusco and on to Ollantayambo then to Machu Picchu the following day. Would you recommend the diamox? One of the travellers experiences altitude sickness when skiing in the Rockies and generally combats that with a seasickness patch. JP
I had a negative experience with Diamox during a trip to Tibet. The side effects, tingling hands and feet, were worse than the altitude sickness it was trying to combat, so we did not even consider that option when we went to Cusco and beyond. The only thing we used there was the local Mate de Coco (a tisane made from Coco leaves. I'm not sure if it made any difference, but we had no altitude related issue other than a mild shortness of breath.
All that being said is that Cusco (3300m / 11000 ft) will be the highest point you are at if you are heading into Machu Picchu (2450 m / 7700 ft). Unless you are trekking, where you would hit higher altitudes at some of the mountain passes. It's called the Sacred Valley for a reason - you will be heading downhill as you head into Ollantaytambo and to Machu Picchu itself.
