Stayed here for 4 nights last week. As a Platinum, I was upgraded from "Deluxe Lagoon View" to "Oceanfront Duplex Bure". There is no Executive Lounge; however, Platinums receive complimentary breakfast (for up to 2) in the Goji Restaurant; Plats also receive a 20% discount on all food & beverage purchases.
My oceanfront Bure was just about the furthest from the reception/ restaurant, making for a 10-minute walk; however, there are frequent golf carts passing by or you can call and request one if needed.
The staff were genuinely friendly, but there were some teething pains evident, especially during busy breakfast rush and the lengthy queues to check in and out. I also had several irregularities on my bill, so best to scrutinize before you depart.
The resort is pretty isolated and therefore options to dine elsewhere would require a much longer (40 min) drive than from Denaru Island resorts. That said, the resort captures the Fijian "Bula" vibe perfectly and I found that I was able to totally relax. It's very quiet and their is good separation from the "child- friendly" and "adult only" portions.
I would return in a heartbeat...
