Hygiene
Yes, Hygiene is super important. In Peru, it was very dirty. There was dog poop everywhere and you couldn’t stand it at all. I wouldn’t even shower since most showers only had cold water and some were even dirty. Luckily, some places were clean so that was a plus. The fact that I went three days without showering is disgusting since during that time most of the hotels/motels/apartments we had been to were dirty.
Internet
There was no connectivity, and cell service would be slow. Most WiFi networks in fact were slow too and wouldn’t even work, your device wouldn’t even connect. In some places, there wouldn’t even be internet so you would be stranded with no connection. To make matters worse, my dad’s phone couldn’t connect to mobile data, so he could only use WiFi.
Elevation
In Cusco, the elevation was super high. I was sick there and took high-altitude pills. Luckily, when we arrived back in Peru, I felt way better.
