Last thing I would say is, depending on your temperature tolerance, I found the diving to be COLD!! So much so that I purchased a Sharkskin titanium exposure layer to go under my 5mm semi-dry. I'm a bit of a wimp with temperature, so you may be fine, but just wanted to flag that it is chilly if you're primarily used to warmer waters.
Right now I’m not used to anything. I have a 5mm wetsuit so that was my plan. Suppose if I need to add something when I’m there I can. My brother-in-law a diver in Hawaii said he mostly just wears a rash guard but he’s got a bit more insulation than me.
We are also going to do some dives on Oahu since that is where he is based and where he’ll be stuck as he’s the one getting wed. I’ll be making some side trips on my own.
