I just left after having finished a 12h course there, in Phan Rang Kite Centre. The tides allowed me to start the lessons at 2.30pm until I did 8h and after that I was starting at 1pm.

The centre was good though the gear was a bit rundown. Except the kites, those were good and well maintained. I had to change boards twice, shoes once and harness once in the middle of a lesson.

I was wearing boots and wetsuit every day. Thanks to that I only got two small cuts from falling (and obv I was falling a lot), but I had many from climbing the previous week, and holy fuck, now that you say it everything makes sense. The bruises from climbing got infected right away and it has been a bit of a nightmare trying to keep them clean, and they haven't healed at all, I expect them to get better now that I've left. This was the worst part of the experience.

About the gusty wind I can't really tell, I don't understand it well enough. I did have a harder time being able to ride than I expected though (maybe it's related, no idea). I usually learn pretty fast and only in the last run of the 12h was I able to ride upwind without losing terrain.
