If you have booked at short notice, this is the safest option to visit Machu Picchu. On the first day, your tour will begin with a bus transfer from Cusco to Ollantaytambo, picking up from your hotel at 3:45 am. Upon arrival in Ollantaytambo, you will take the train to Aguas Calientes, where you will arrive at 8:00 am, as early as possible. In Aguas Calientes, you will proceed to obtain your service number at the Ministry of Culture, which will allow you to manage access to Machu Picchu. Afterwards, you will have to return in the afternoon to pick up your ticket for the next day, thus ensuring your access to the famous Inca citadel.
