Fairly fresh off its Starwood Hotels & Resorts acquisition, Marriott International on Tuesday said it plans to add an additional 285,000 to 300,000 rooms worldwide by 2019. CEO Arne Sorenson pegged the company's optimism to continued growth in global travel spend, projected to increase at a 7 percent compounded rate over the next 10 years, according to the World Travel and Tourism Council. Sorenson, in a presentation to investors, pointed to China as a particular area of opportunity, with travel spend for the Asia/Pacific region forecast to grow at a 9.5 percent compounded growth rate by 2026.
