re: Common mistakes when traveling internationally?

My first mistake was in packing, I brought WAY too many clothes.....

Wasn't sure about the weather as Google kept saying the nights were in the 50's or 60's so I brought some light jackets and they were never needed.

I probably only wore 60% of what I brought because we had access to a laundry mat a block from where we stayed and the hotel did a laundry service as well.
