In November the north sides of the islands are iffy/shut down to diving by weather. So Kauai would be a bad choice since that includes the best shore dive - Tunnels - and the best boat dives - Ni'ihau.
Nice thing about Maui is you've got accessibility to 3, possibly 4 islands to dive. There's decent shore/boat diving along the West and South Maui coasts - many opperators do 2nd dives there at a dozen or more sites generically referred to by some as "Turtle Town" - there's all this shorediving -
Scuba Shore Diving Site Listing for: Maui, Hawaiian Islands and if you select the right condo properties - some in both Kihei/Wailea or north in Napili - you can dive from the beach out front of your resort.
Also there's all the boats diving Molokini Crater from the Kihei boatramp, a few options from Ma'alea harbor generally to Molokini also - depending on conditions inside the crater are good dives, there's dives off both points and the Backwall which is very vertical to about 300' and a good option for sharks usually.
From West Maui the boats go to Lana'i for the Cathedrals or the West Lana'i drift dives. I personally think the west Lana'i dives are better than Molokini - certainly more vertical in some spots and the fishlife is superior to anywhere in the crater except where the snorkel boats feed them. I've seen 4-5000 (DM estimate) tangs holding station off Sharkfin while 1/2 dozen reef sharks waited for dinner - the only place I've ever seen that.
Possibly in November Lahaina Divers is still also going to Moloka'i to dive with Hammerheads but it may be too rough.
So Maui is a good choice. Plus the shore dive entries are a lot easier than on Kona - many beaches instead of lava. Even the carries are often shorter. Parking will be an issue at some of the South Maui sites so either go early or in the afternoons. If you do plan to shoredive, tanks are available at 4 of the Maui Dive Shops, B&B Scuba or Maui Dreams Dive Co. in Kihei as well. Probably Lahaina Divers also - I think we rented from them once.
All of the Kihei boats are smaller - some operators pull theirs out at the ramp daily. None are over 12 divers IIRC Mike Severns could be an option for you there. Or Maui Diamond II - booked thru Maui Dreams Dive Co. in Kihei also - just a short drive to Ma'alea. While there - or make the drive later to the Maui Ocean Center also. I'm also a B&B Scuba fan - they're the nicest people.
In Lahaina, Lahaina Divers has two 46' Newtons but they're not overly crowded as they have an upper deck also. Or Extended Horizons - I think 12, maybe 16 is the max capacity of the boat.
All operators generlally work to an 8 divers/DM ratio. I've been on Maui Dive Shops boat with about 22 others - so a little awkward gearing up but once we hit the water we never saw the other groups again - they sort by experience level.
