I loved going to Machu Picchu staying at the Sanctuary Lodge but I have a word for those suffering from vertigo,you'll probably won't be able to see the ruins if you're not very very fit.The easy way is close to a deep gorge and we sufferers know we won't do it and the hard one is very steep for those not so fit.The mountains and the train ride are really beautiful even if you can't see the ruins.After I got there I met many people with the same problem (vertigo) who were't able to go to the citadel
