Our theme for DAK is simple and practical: quick-dry.
It's a park where kids WILL get wet (between Kali and the fountains, and it's always hot, too) so everyone in our party always makes it a point to wear wicking sport-clothing to DAK. This includes Amphibious sandals, quick-dry shirts, and lined shorts that prevent having to walk around in wet underwear.
(BTW, if you go to IOA, this is even more true, as nearly half of the rides there involve water.)
