I've looked at several of my photos, which are time stamped, but its tough to give specifics about the time of day for each wing. We were on the third floor of the Waianae Building in villa #304, and we got sun before 8:00 AM to 4:00 PM or so. The Ewa Long Wing odd numbered villas (xx71-xx87), which face away from the pool, are partly in the shadow of the Ewa Short Wing, but they should have the sun for almost the same amount of time. The Ewa Short Wing even numbered villas xx60-xx68 will miss the morning sun, but should get sun at midday until late afternoon when the sun is blocked by the Ewa Long Wing.
As I said in my previous post, its best to look at the resort map in Post #1 and imagine the sun moving from the lower left to the upper right.
By the way, the Aulani Villas have sheers. Guests don't have to worry about their villas getting overheated by direct sunlight.
