Go early. It’ s worth it to stay overnight in town so you can be the first through the gates. It’s so beautiful and quiet before the tour buses show up. Around 10:00 tour buses will arrive and drop off crowds people.

Rent a bike (test it first- a lot of them have bent handlebars) and you will be so happy. A bike will get you around fast so you can see the whole place and save your energy for trucking up the steep stone stairs to the top of the pyramid.
