We had our honeymoon in Fiji and stayed at the Shangri-La resort. It was just perfect! we went in 2005, so not sure how much has changed.....but there were 3 different pools, quite a few restaurants, tour desk, money exchange, games room, sooooo many activites/sports/fun competitions etc. And their kids club was awesome! the ladies who worked in there were so happy and friendly.
I remember the meals being a bit exxy, but their buffet was great! so much variety and everything seemed really fresh. But their alcohol was very over priced so I highly recommend buying duty free as someone else mentioned.
