The cooking class... Exactly as you describe! We loved the early morning trip to the market to shop, then to the local home to slice / cut / grind / cook. And the bale overlooking the Ayung - we loved it!
We really liked the main pool, and used it nearly as much as our plunge pool. The infinity edge off over the canyon was wonderful. We would swim in the evening too, as the gamelan players were playing on the platform. We did not feel self conscious at all, but others might.
We did the Ayung river rafting too, and it was fun to end right below Amandari and walk up the steps, across the rice paddies, and back to the resort.
