Stay At The Sanctuary Lodge
The only hotel at the entrance of Machu Picchu, the Sanctuary Lodge is pricey, but has a hot tub overlooking the ruins (kind of) and makes it easy to get to the park very early with ease. If you are tight on time here I would highly suggest.
Sunrise At The Sun Gate
Rise early and hike up to the Sungate to experiene sunrise over Machu Picchu.
