IHG Hotels & Resorts, the official hotel partner of the US Open, is embracing the playful debate surrounding the color of a tennis ball with its ‘IHG Rally Room’ and other unique experiences at the tournament. The ‘IHG Rally Room’ is a themed suite offering guests a chance to experience the ‘green’ or ‘yellow’ side of the debate, while the Grand Slam Social event features an exclusive DJ set by Mark Ronson. IHG One Rewards members can also enjoy exclusive benefits at the US Open.
