One flat fare, then an add-on. For 3D2N the whole boat is IDR 106,000,000 (≈ USD 6,503) for 1 to 12 guests. Each guest from the 13th to the 18th adds IDR 5,000,000 (≈ USD 307). The same logic holds on the other routes: 2D1N is IDR 83,000,000 (≈ USD 5,092) plus IDR 4,000,000 (≈ USD 245), and 4D3N is IDR 153,000,000 (≈ USD 9,387) plus IDR 6,000,000 (≈ USD 368).
Twelve guests pay IDR 8,830,000 (≈ USD 542) each, sixteen pay IDR 7,880,000 (≈ USD 483) and eighteen pay IDR 7,560,000 (≈ USD 464). Park tickets and ranger fees stay outside the fare, at any party size.
If Semesta Voyages cannot sail, the date holds on a phinisi of equal or higher standard at no extra cost, or you take a full refund within 14 days. A breakdown and a port or park order both count.
