Fiji bound!

Hi everyone! My husband and I are heading to Fiji in October for our honeymoon. Not sure where to stay and were hoping for some good recs. We’d like to keep the housing sitch under 5k for two weeks and we are hoping to absorb as much beauty as possible. I’m kind of overwhelmed with options. Is it recommended to stay in one spot for a whole two weeks or try out a more secluded location for half and a more main location for the second half? Open to all suggestions!
