Today, Hilton manages nine hotels with a total of 3,400 rooms under Hilton (four hotels), DoubleTree by Hilton (four) and Hilton Garden Inn brands (one). These include new-build properties as well as existing properties that have changed hands and/or operators.

Both have new owners. Hilton does not own a stake in any of the properties it manages in Malaysia.
