Island for Solo Female Traveler??

Hi all...

I am heading to Fiji for a very short 5 night break by just by myself (to get away from a hectic life) ... I am 27 and want a bit of a chilled break this time as opposed to partying 24/7 .... I want to do a fair bit of walking and snorkeling / swimming in crystal clear waters......would also love to meet other solo travelers.....any suggestions as to what would suit me best?? I've seen a lot of recommendations for Octopus??

Cheers!! Happy travels!!
