12 November days in Fiji - What should I do?

Here is a list of things I’m interested in. I have 12 full days there in November and I get the sense I don’t have enough time to do everything (isn’t that always the case). Hoping to get some feedback on which are must-sees and which maybe aren’t as great as I think they are.

If there is anything else you’d like to recommend feel free to do so. I just pulled things for the LP Fiji book so I’m sure there are tons of other things to do.

Additional questions:

-Would it be a crime to skip the Mamanucas and Yasawa group? It’s not that I don’t want to go there – the list just seems too long without them.
-What beaches would you recommend to someone from Hawaii that has super high standards for beaches?
-Is it possible to sea kayak in November?
-Which hikes are not-to-be-missed?
-Recommended snorkel or dive sites considering geographic location of my other interests?
-Any advice or contacts for arranging tours of local farms?

Asterik indicates things I’m super interested in doing – pls warn me if I’m disillusioned.
