I've tried to locate any time available at the resort but never found anything available.
Since you asked for other resorts in Maui, the best ones (in my opinion) are the Westin or the Marriott but I believe those only trade with I.I. I think the Westin is so nice we just bought (resale) a Oceanfront 2 bedroom -- might be the only way to easily get in.
Another recommendation: It's a lot of points, but the Grand Wailea is our favorite resort on the island. Have you tried that one? I'd recommend using your points for the cheapest room and then purchase a upgrade at check-in (if available). The resort is so expensive, and I feel the value is decent to use our
DVC points for the experience.
Good luck!
