Format
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.
Guest sentiment
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.
Who it takes
Both are adults-only. Neither is a compromise for couples wanting quiet.
Getting there
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.
Scale
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.
