AFter not being able to book a trek, we decided to do the cheap option... we took a local bus to Ollytantambo, took the cheap backpackers train from there to Aguas Calientes, stayed in a hostel and then got up at 4 am to climb to Machu Picchu on their winter Solstice to see the sun rise! Excellent. Did loads of walking up the surrounding mountains. Really enjoyed it, but really knackered now! Heading to Cusco for the Festival of the Sun.
