I very nearly had to spend 21 hours in Zurich. …while a lovely city, I was just planning to fly through it to my final destination. I was on Kayak, one of my favorite travel sites which I use religiously whenever I travel and it has never caused me an issue. However I usually typically only use Kayak as a search engine and not a booking service, although the last few trips I took I booked directly via Kayak and everything went smoothly.
