If you've been looking at the Discover Fiji website, beware of booking with Air Pacific, which seems to be the only carrier for Fiji.
Make sure you know exactly that you want to go as there is no refund should you cancel, even if you cancel immediately.
I booked online with them and the money was charged to my credit card immediately but needed to cancel the next day. In fact, the e-ticket still wasn't even issued 4 days later. The HK office will inform you that it is refundable but the main office will insist on you paying the cost of the flight and just refund the cost of taxes.
So just be careful if you book.
