MGM Mirage, the world's second- largest casino company, plans to almost double gaming tables for high rollers at its Macau casino by year-end to tap the growing number of gamblers who spend more than USD 124,000 a visit. MGM Grand Macau, a venture between the Las Vegas-based company and billionaire Stanley Ho's daughter Pansy Ho, will increase its VIP tables by 70 to 150, Chief Executive Officer Terrence Lanni said on a conference call today.
