If it was me, JJJ, I'd check the weather forcasts / climate data for fiji and this time of year. My recollection is this is still during the wet, when you'll get little opportunity for clear skies... but I could be wrong

.
If there's a good chance of clear skies I'd say take it! Take it all!

But, if the chances of clear skies are slim, just take a minimalist kit (and hope

) and otherwise just kick back and enjoy.
