Machu Picchu is unmissable, but it’s also a massive rip off. So was it worth it?

This may be controversial... but from start to finish, we felt milked by Machu Picchu. It cost us the best part of ยฃ800 over 2 days. Are the Peruvians ripping everyone off? Can you really blame them? Or could there be a cheaper way of doing it?
