We were there in May, checking in on Sat the 20th for a week. So we overlapped some of your days. While checking in, we spoke with the person who brought up our luggage and he said we were lucky. The week ending was at 90% capacity but the week we were there was 70%, and it would go back to 90% after we left. It had something to do with the school year ending on Friday the 26th. I have to say we never felt like it was crowded at all. We didn't need reservations at Ama Ama for either breakfast or dinner, but were told by our server that we would have probably needed them the next week. If it were me, I'd stick with what you have, since after the calendar turns to June it sounds like it gets pretty busy. Too bad you couldn't move it back a few days.
