Planning a trip in early July to Machu Picchu and Cuzco, but wondering if it makes sense to stay a night in Ollantaytambo too?

Most likely 2xCuzco, 1xOllantaytambo, 1xAguas Calientes (Sanctuary), 1xCuzco and then depart the next day for overnight flight from Lima.

Any travel tips to make the best itinerary would be most welcome! And any tips on transportation while in Peru would be most helpful as well.

Thank you.
