The scenery was stunning. And actually day 2 is not that bad ! Although I would definitely recommend a porter. Machu Picchu is surreal. And definitely worth the early morning wake up. Be prepared for the horrible toilets and I would advise baby wipes and a shower on day 2 even with the cold water.
The food was great but pace yourself with the happy hour ! Our Guide was a nice guy called Marco Antonio Carbajal - from whom we thankfully rented walking sticks - which I would highly recommend. He was very friendly but don't let his chat about the final day scare you.
