I was there for 15 nights in July. We split it between the main island and plantation island. Hideaway was a great place on the main island with friendly staff and an atmosphere that creates friends between the guests (lots of beer drinking Aussies

).
Plantation was very good but I think Treasure and another I can't remember but you can see the isalnd from Castaway (Malolo perhaps?).
Lots of great beaches and diving/snorkeling that I would do from the outer islands.
Bula,
