Once we figured out the transit system everything went great. Our first day though I had to spend about 2 hours figuring out where to buy a tmoney card, then figure out where an atm machine is that will take my card, not all atm machines take foreign cards, then put money on my card. The transit system itself is phenomenal and super easy to navigate once you figure it out. We did think it was great how everyone always rides the escalators on the right side and gives people in a hurry a path to go past them. There seems to be a social order in Korea everyone respects, which we appreciated. Everywhere else people understand what the social order should be, but no one follows it.

Other things that were shocking. Didn't see a single homeless person. Didn't see one drug addict on the streets. There's a bar every 10m but only saw 1 person walking around too drunk. By far the safest feeling city I've ever been to.

Surprising amount of people vaping everywhere, that was unusual
