The Hai Tide Huts are very nice. I stayed there in 2000. They are individual thatched huts on stilts. Very comfortable. The food there was delicious. The diving is right in front of the resort, although you will still need a boat.
I LOVED Blue Corner. I was determined to dive there after reading the narrative in the Bali dive guide. The first line is "DON"T TRY THIS AT HOME!". It describes the incredible currents (straight, upwelling, and down currents). I knew it was going to be something when we arrived at the put-in and saw the area full of huge boils in the water. The first dive was scarey, the second-amazing.
You will have a great time.
