It was a great trip. The rooms are comfy, the food is excellent and plentiful. The staff is great (especially Captian Guy). Like all Aggressor boats they cater to photographers.
They don't allow anyone to dive w/o a buddy unless they can show a solo diver c card. Other than that you are pretty much left to dive your own profile. They generally hit 2, maybe 3 dive sites a day. They will park at the site and tell you the pool is open. It's then up to you to do your dives(up to5 a day), and ensure that you spend appropriate time on the surface in between.
All dive sites are within swimming distance of shore and there can be quite a bit of surge. You get used to it after a few dives and it can actually be fun to ride it back and forth.
I really enjoyed diving in Hawaii. Although it doesn't have the diversity of other areas it does have a high percentage of endemic fish species. You will see things in Hawaii that you can't see anywhere else in the world. Also, the volcanic nature of the islands makes for some pretty freaky underwater topography.
The thing I think I liked best about the trip was waking up in the morning ans seeing the sky over the most beautiful coastline I have ever seen.
Book this trip. You won't regret it. If you go, take a small plane ride around the perimeter of the island. It's definitley worth the money.
I want to go back.
