A tour company I'm considering using quoted me $650 for 2 day MP tour including train from Olly, private guide for 2 of us, overnight in hotel in AC, 2nd day MP entry and hike HP and train back to Cuzco. Does this seem right? They say guide for 2 is expensive but we don't necessarily need a private tour. Can we hire a guide at MP the day of and travel to/from ourselves. I've never used a company before and I'm not sure I need to start now.
