In 2026, the title of the world's most expensive resort per night is often held by Lover's Deep Luxury Submarine in St. Lucia, which can cost approximately $235,000 per night. This "resort" is actually a private luxury submarine that takes guests on an underwater voyage with a personal chef, butler, and captain. For land-based stays, Banwa Private Island in the Philippines and the Royal Mansion Suite at Atlantis The Royal in Dubai frequently top the lists, with rates starting at $100,000 per night. These ultra-exclusive destinations offer total seclusion, with Banwa requiring a private helicopter or seaplane transfer and offering a 15-acre sanctuary for just one group of guests. Other high-tier contenders include North Island in the Seychelles and COMO Laucala Island in Fiji, where "Hilltop Villas" can reach $60,000 or more. These prices typically include all-inclusive gourmet dining, private spa treatments, and dedicated staff, catering to high-net-worth individuals who prioritize absolute privacy and bespoke service over traditional hotel amenities.
