+2 on the Beachouse
www.fijibeachouse.com/ it's half way between Nadi & Suva on the Coral Coast about 1-1/2 drive from the airport , such a cool beautiful place. Fantastic family place with surf straight out front , super sup friendly. The owner Andrew Brown is really into Sups he has boards their to hire , plenty of boats to take you to other surf spots.
Re the boards Air Pacific charge $50 each way per oversize bag so put your paddle inside the board bag , pretty sure you can take almost 10ft board. Virgin is the other option cannot recommend Crapstar.
This is some of my pics...
