Most of my friends -- a spread of PhDs, teachers, well-off tech workers, and blue collar workers -- have barely left the USA. I really enjoyed the time I spent in the UK for a college semester. It permanently ruined the US city experience for me -- even NYC is not as walkable as the small-ish city I lived in.

When my friends do leave the USA, it seems to largely land them at resorts, or guided tours, or other "on rails" tourist experiences that disconnect them from the day-to-day life of people who live in those places. Meanwhile I visit cities to explore on foot. I plan on doing some European bike tours soon to experience some of the small towns and countryside that I've previously missed out on.

Considering how much my friends and family love the walking and public transit experience at Disney World, I wonder how much they would enjoy just walking and taking public transit around other cities around the world. It's really not that different.
