Definitely on the casual end of the spectrum - I can’t even remember needing tickets, although I suppose I must have! The opening/closing ceremonies, Kok-Boru (crazy, but well worth experiencing) and wrestling/floor-events were in proper venues - the Kok-Boru one is a permanent stadium, but if I remember right the wrestling ones were temporary constructions for the event, both on the edge of lake Issyk-Kul. The rest was essentially in a field in the middle of nowhere - public transport was either Marshrutka, or as I learned on the way back hitchhiking is much more efficient - and it was all pretty easygoing as I recall.

Really recommend it; Kyrgyzstan is a beautiful country, sparkling rivers that are so blue you could almost think they were dyed running from snow-capped mountains through green plains below… Amazing place. And I found the Kyrgyz people to be some of the most friendly and hospitable I’ve ever met (although I know that sounds trite and everyone says that about wherever they go, but still, it’s true.)
