Chinese travel platform Fliggy is selling F4 membership for 188 RMB (about $25–$26) that activates roughly four months of Marriott Bonvoy Platinum and Hilton Honors Gold, according to travel sites and reader reports. The offer includes an eight‑night requirement during the trial window to extend Marriott Platinum by about a year or more, with similar mechanics reported for Hilton Gold. Coverage describes widespread publicity in China that has made the challenge broadly accessible, not just to points enthusiasts. Readers and analysts report operational strain at hotels, including crowded breakfasts and lounges, scarce upgrades, and friction over late checkout. Reports note repeated account cycling and some gray‑market reselling, while analysts suggest Marriott appears aware through a partner arrangement, though no formal statements were cited.
