Would you mind sharing some more information in terms of your visit? Is this a family trip, something with just your partner, would you like to see a ‘off the beaten track’ type of trip or more staying near the resorts?
For some reason my family have taken a liking to Fiji over the past few years and we’ve gone over a few times – as much as I love Denarau I think you should definitely spend some time on the smaller islands. If you’re travelling later on in the year I’d recommend Mana Island (they’re about to start renovations on a lot of their resort and it should be done by the end of the year afaik).
