For the wiki version, you have <a href="https://www.wikivoyage.org" rel="nofollow">https://www.wikivoyage.org</a><p>It can be a bit outdated, but then you just update it as you do your research ;)
For Seoul, I think this is an interesting observation:<p><pre><code> Seoul is not a pretty city, at least not by most Western standards of beauty.
It is a sprawling, haphazard mix with little apparent cohesion beyond a shared culture.
</code></pre>
Personally, I really liked it because it has a different vibe from a more "sterile" city like Tokyo.
Thx, great read about Yemen from Maciej Cegłowski <a href="https://idlewords.com/2014/07/sana_a.htm" rel="nofollow">https://idlewords.com/2014/07/sana_a.htm</a>
For Switzerland, for someone who likes railways, I found this guide (missing from guide.travel) to be quite nice: <a href="https://www.seat61.com/train-travel-in-switzerland.htm" rel="nofollow">https://www.seat61.com/train-travel-in-switzerland.htm</a><p>While planning the trip, I was annoyed by redditors on r/askswitzerland ending almost all replies by asking folks to download the <i>SBB Mobile</i> app. To my surprise, even though I'm not the kind to install apps (let alone Flutter apps), it was god-sent. So well made (their "design system" is open source: <a href="https://github.com/SchweizerischeBundesbahnen/design_system_flutter" rel="nofollow">https://github.com/SchweizerischeBundesbahnen/design_system_...</a>). Makes travel up and down the country, from Zürich to Lugano, from Genève to St. Gallen, from Basel to Campocologno, stress-free.<p>For tourists, TooGoodToGo.com (mystery meals) & SwissTopo (trails) are equally neat.
