We dove with Cook Island Divers on Rarotonga, with a DM named Ian, and we had a wonderful time. Rarotonga had the same problems with crown of thorns starfish and dead coral that we saw elsewhere, but the dive we did had a lot of swimthroughs and a lot of reef fish, and we saw a Spanish Dancer there, which made the dive for both of us. I really liked Ian, and I REALLY liked it when he said, "There's no time limit on the dive; it just depends on your gas." THAT was different from the other places we had dived, where the dives were 40 to 45 minutes, and I was coming up with 1400 psi.
