DH and I went October last year, and a couple of our friends went a few weeks back on our recommendation...

It's wonderful. We stayed at Denarau, and you can pick hotels for kids or without kids... It's pretty affordable, great food... people are really friendly and they smile a lot lol.
You can hotel hop at Denarau which is fun, there's a cheap little bus that can take you around. Taxi's aren't very expensive and there are all sorts of tours to suit your experience requirements.

As a nice relaxing warm place to go, it was super.
