Not bad. there is really only like 1 1/3 schools there.
Kite kuda operates between 9-12 and 2-5 during which it can get crowded in parts. There is still plenty of space, it's just the prime area on the lagoon gets busy. The rest of the day though the lagoon is almost empty.
The wind is all day. Therefore, if you want to beat the crowds start before 9 or kite while kite kuda is on lunch or in evening, or even nighttime. 24 hour wind ensures that you get your fill of kiting. I still have blisters on my hand from my last trip a month ago.
I've had two collisions there myself, and seen about 20 others. These are usually beginners, or people not observing the right of way (Russians).
