I've done KOH a few different ways. Mostly because of work. One weekend. Mid week, Both weekends, and all week.
By far I had the best time last year staying out there all week. 10 full days. So that's my hope again this year. Sorry moto dudes.
I was able to get involved in a few clean ups, go to the fun events like Ultra 3, host some stuff like the Night Run we did with
@Baja Designs , AND THEN even take a night or two off to hang out and do nothing besides cook and hang.
So the longer you stay the better I feel. There is just a lot of do and be a part of if you look for it. Basically treat it like a festival.
