I'm on the Fiji or Vanuatu team - I have been to both those, Bali and Thailand and especially while pregnant, I would be going the shorter flights. I went to the Maldives 13 weeks pregnant which was very long and uncomfortable so any more pregnant than that would be even worse I am sure! Fiji flights are on sale some times, I went about a year and a half ago and paid $200 one way, was very happy! And the flight is only about 4-5 hours from memory? I don't know if I would want to do more than that, but stayed at a gorgeous, beautiful place and lots of blue water and powder sand - just like you'd hope for on a relaxing holiday. You also need to worry less about food and water issues like they have in Thailand and Bali. I was very vigilant in Bali, brushed teeth with bottled water etc but still ended up with an upset stomach by the end of the trip!

Audax - wow that sounds amazing. What a lucky woman.
