June is a rough month to get a single room at the 7 month mark at Aulani let alone booking three. The more expensive the room the better chance you will have. What I mean it is easier to get an ocean view versus an island view. In fact many of the island views are usually gone by the 7 month mark by Aulani owners. Like OKgirl said book right at the 7 month mark and hope for the best. You might end up with three rooms with different views.
