I think for some places, it is better going with tour and knowledgable guide. For those Inca ruins, you actually can go on your own if money is not problem, and you can do your homework before visiting those places. :))
I had my caculation and thought it would be cheaper so I took it. 😁

You’re in Cusco already? Heading to Machu picchu?
I bought a poncho in Cusco 2 years ago and now it is still amazingly good.
Promise me that you gonna have Machu Picchu photos wearing those beanie and headband. I’ll check your blog. 555
