Aloha!
Did you take a look at the Maui Prince? Far from Ka'anapali, I know, but that could be a good thing.
There are a lot of posts in FT Miles - Marriott on the Ren. Wailea and the other Marriott properties.
The Westin is nice - I like the new tower.
BTW, There was a good thread on this board a few months ago for Maui.
