The Shangri-La Fijian is the most amazing place for kids and adults! I went every year as a kid and the kids club they have is so amazing, easily my favourite place in the world. They also have babysitters.
We went back to scatter my dads ashes there a few years back after not going for about 4 years and they all remembered us and threw a beautiful cava ceremony for us and then took us out on the boat.
I also plan on going back in the next year or two to get married
