Round by round
Royal Davui Island Resort is a private-island resort: 16 villas, one restaurant, and no way off it without a boat. Emaho Sekawa Retreat Fiji is a mainland retreat on Vanua Levu, which is a different kind of isolation.
Both sit at the top of the range, with Emaho Sekawa Retreat Fiji holding a perfect or near-perfect record across a small review base. Small samples move fast, so read the category scores below rather than the headline figure.
Both are adults-only. Neither is a compromise for couples wanting quiet.
Neither is a short transfer from Nadi. Royal Davui Island Resort involves a boat to Beqa Lagoon; Savusavu is a domestic flight away. Budget a travel day either way.
16 villas at Royal Davui Island Resort, fewer again at Emaho Sekawa Retreat Fiji. At this size the resort is effectively private, and service scores below carry more weight than any facility count.
The verdict
Royal Davui Island Resort is the one to book for the island itself: sixteen villas, your own reef, and the Beqa Lagoon outside. Emaho Sekawa Retreat Fiji answers if you want something smaller and more personal on Vanua Levu, and its guest record is extraordinary even by Fiji's standards. Both are travel days from Nadi, so decide on setting rather than convenience; convenience is not on the table.
