Fiji

I need suggestions from people who have been to both. Where can i get sickeningly amazing views and beaches? where is teh place to go for a dream holiday. Is one more expensive than another? I will be traveling from London, UK and I am not sure when so the weather is important, when is best to go for both? Please help! ;-) Thanks

I am getting married in August 11th and would like to honeymoon in Australia, New Zealand and Fiji. I would like to relax a few days on a beach and spend the rest of the time hiking, off roading, snorkeling, diving, etc. Any suggestions on good places to go in any of these areas? And will it be too cold? Thanks.
