You don't really have enough days to get out To Thailand or Indonesia so I suggest you look for something closer. A lot of those trips are 10 days also plus probably 2 days flying from TN.
The other issue is that this close to sailing a lot of trips will be full. 3/4 of the Explorer Ventures boats are.
However they have space on the Turks/Caicos boat which is also a really great trip, lots of sharks, deep wall diving and macro around the coral heads. Out at French Cay we saw one or more sharks on every dive over 2 days - also dozens of rays. And turtles. Generally the visibility is exceptional and now it will be really warm. With thanks to Mike Southard - more trip detail:

It's a good boat, good crew and there's a lot of space. If you buy a main deck cabin space they have twin beds - not bunks - and windows. Only the 3-4 least expensive cabins a deck down have bunks/portholes but they're still ensuite. The boat is about 15 years old but built to be a dive liveaboard - not converted. One thing I liked is the covered fly bridge a deck up from the sundeck.
From TN it's probably fairly easy to get there. We flew thru Charlotte and were on Provo (Providenciales) by about 1PM. They met us and took us to a shopping area for lunch and our gear to the boat. If you need it, there's WiFi at the dock. Otherwise not much access, both West Caicos and French Cay are uninhabited.

This close to sailing I'd call Explorer Ventures and confirm the details.

I checked Rocio Del Mar but they're sold out your week. That would've been my other suggestion since you fly into Phoenix and shuttle down.
