Fiji - North part of Viti Levu / Wananavu Resort

My wife and I will be passing through Fiji on our way back to America. We've done quite a bit of searching and have narrowed our list down to a couple resorts to stay at... one that I can't find much info on though is Wananavu on the north coast of the main island.

Can anyone give me their perspective of the resort and the Rakiraki area?
-Is there reasonable snorkeling off the beach there?
-Any experiences of Wananavu Resort itself?
-Is there anything to visit in the area (including day walks)?
-Is there a reason why it is the only resort in the area...compared to the Coral Coast?
-We've worked out the price to be +/- NZD 375 /day for 2 adults (all inclusive & 17.5% tax included)... has anyone found a better rate?

Thanks for your help!
