It is important to clarify that as of early 2026, Treasure Island (TI) Hotel & Casino in Las Vegas has not closed; it remains fully operational on the Las Vegas Strip. However, there has been significant "closing" of its original theme and identity over the years. When it opened in 1993, it was a family-friendly, pirate-themed resort famous for its free "Battle of Buccaneer Bay" show. In 2003, the resort began a "closing" of this era by rebranding to "TI" and replacing the pirate show with the more mature "Sirens of TI," which was eventually cancelled in 2013 to make way for a retail pharmacy and shopping area. If you are referring to the Treasure Island in Florida, it is a city/beach destination that frequently faces temporary "closures" due to hurricane damage and beach erosion. More recently, in the world of entertainment, the "Treasure Island" music festival in San Francisco has faced long-term suspension and "closure" due to development projects on the island itself. In the context of the Las Vegas resort, while the property is very much alive, the whimsical pirate-themed "Treasure Island" of the 1990s is considered "closed" and replaced by a more conventional, adult-oriented hotel experience.
