Just to bump this post up, I want to second Thunderroad's recommendations for both the Conrad Bali and Wayan. We used points to spend 6-nights at the Conrad and had a truly phenomenal experience, and Wayan is exactly as described: very knowledgeable, very outgoing (without being too much), and very flexible. We made a number of stops, including at a traditional Balinese home, a temple, and the rice fields, and I really feel like we got a great sense of the island in a day. We recommended him to another couple at our hotel, and they had a terrific experience as well!

Feel free to PM me if you need any other details.
