One couple in our group got engaged on the top of Machu Pichu. Unfortunately the guys fingers were swolen due to the altitued so his ring was difficult to get on and impossible to get off. His finger started to go black and in the end they had to cut the ring off with a hack-saw. It was a Platinum ring therefore the cutting was no mean feat given the location.
I had a lie in and walked around town, then went down to a thermal spa. Went to a disco which was empty until we showed up. After we had a few cervejas we where dancing around the place though.
