Just decided (this morning) I want to take the missus on a holiday in September. I would also like to make it a kite trip

the options are Fiji or Cocos. Just want to kick back, relax and kite.
Interested in pro's/cons of the two destinations. Keeping in mind my missus (who doesnt kite, but may take a lesson or two) is along for the trip.
The zephyr kite tour/location looks the goods, and Fiji...cant seem to find much definitive/positive info on kite locations, places worth staying etc.
Over to you...
