The total number hotels owned by Marriott International is now 5,700 with more than 1.1million rooms spanning 30 brands in 110 countries.
The acquisition was delayed last month after the two companies announced that they had agreed to extend the time period for the Chinese Minister of Commerce (MOFCOM) to complete its review of the merger.
Marriott International has now merged the Starwood Preferred Guests (SPG) and Marriott Rewards loyalty programmes. This means guests can redeem their points across the Marriott expanded portfolio.
John Marriott Jr, executive chairman of Marriott International, said: “With the addition of Starwood’s strong brands, great properties, and talented people, we have dramatically expanded our ability to provide the best experiences to our customers.
“We also welcome the tremendous responsibility as the world’s largest hotel company to be a good global steward, providing new opportunities for our associates and building the economic strength of the communities we call home.”
Arne Sorenson, president and CEO, added: “We can now provide a better range of choices for our guests, more opportunities for our associates, and greater financial benefits for our owners, franchisees and shareholders.”
