We will be spending 3 honeymoon nights in Fiji (probably Mamanuca since I prefer not to take a seaplane). Do we have enough time to take a ferry from our resort to Nadi - if our flight leaves Nadi at 9am for Sydney? Do we have to spend the night in Nadi the night before? How long is the ferry from Nadi to Mamanuca (possibly Likuliku resort)? Thank you.
