After hiking the Inca Trail and spending an extra night in Aguas Calientes, we will be taking a morning train back to Ollantaytambo, getting in around 11am. Is it possible to find a tour guide/tour company that would take us around to the ruins in Ollantaytambo (or are they walkable from the train station?) . Then, we will need to get back to Cuzco for the night. Could either take the bus, or possibly the driver could drive us back to Cuzco? Thoughts? There will be 4 of us-2 adults and 2 children. We're trying to do this semi economically.
