Fiji in mid to late September through into early October will be over-run with families on Spring vacation break from Australia and New Zealand.

Do take everything with a grain of salt, do get used to & just accept "island time" is a fact of life, (where a "Yes we can do that" can mean "we can do that but it may be tomorrow, 2 hours, two weeks), do go and enjoy the culture/heritage, do go with open minds and accept the smiles and inquisitive questioning from the locals as real genuine queries and not people passing plain old pleasantries.
Don't get stressed about things being worked on on "island time", don't expect everything to be hunky dorey and working to plan, don't get sucked in by the "artists" selling their wares!

In short, a beautiful nation with beautiful people for the most part, which is true for all the South Pac island nations. Just avoid all the spring breaking Ozzies and Kiwis with kids!
