So, I'm fairly new to this. We own at AKV, and have been several times, also to a couple other central Florida resorts. We would like to go to Aulani December 17 to 27, 2014. I'm worried about availability though when I am finally able to book it (in May). If we can't get in there we would go to AKV for the same period. My question is - should I book AKV now, while it's available (using current years points and borrowing from next year), then attempt to change to Aulani in May? Would that work? Any penalties? Any downside? Thanks for any input!
