In season five of "The Office," Ryan claims that he took a long trip to Thailand.
The claim appears during the aftermath of Ryan's corporate scandal and firing. When he returns to the Scranton office, his appearance has changed: he has a tan and bleached hair, details that help sell his story about an exotic overseas trip. His coworkers accept—or at least entertain—the explanation that he visited Thailand.
The joke is later revised when Michael reveals that Ryan did not actually travel to Thailand. Ryan's supposed international vacation was really spent in Fort Lauderdale, Florida. The deception fits Ryan's broader pattern of trying to reinvent himself and appear more impressive than he is, especially after losing his corporate position and facing legal consequences.
Because the question asks what Ryan claims, Thailand is the canonical answer. Fort Lauderdale is the later reveal, not the country named in his original story. This distinction matters: a question asking where Ryan actually went would have a different answer, but the wording about his claim makes the stored answer correct.
