i used to live in Fiji and TOTALLY second getting out to the islands. they are exquisite! the mananuca group and yasawa are the easiest to get to and have heaps of different ranges to choose from in terms of hotels etc.

we enjoyed plantation island resort as a getaway that was a bit more spesh (usually we went local and headed to the islands on the other side of the island lol). if you want total indulgence i remember all the UN people etc would head to the Royal Davui....omg, everything i heard was preeettty nice LOL! (unfortunately our local wage couldnt justify it LOL!).

places like treasure island etc are popular but tend to be frequented by families and TBH have some dodgy practices in terms of ripping off people buying packages. avoid Bounty Island (sometimes sold as a lovely hotel island...lovely island, but VERY rough in terms of accom).

if you want idyllic beaches and superb snorkelling head to either of those two island groups and you wont be disappointed. you could be disappointed if you go anywhere along the coral coast. lovely hotels/resorts but NOTHING in comparison to the islands in terms of beaches and snorkelling IMO.

oh and for spesh i have heard that turtle island is really amazing...apparently 'our' nicole (kidman LOL) went there a couple of times...pure island gossip though LOL!
