Melco Crown's (MLCO -1.28%) City of Dreams is one of the most profitable resorts in Macau, and the company is expanding to bring in more guests. It recently announced its fifth tower, and with a unique design, it will change the landscape of Macau's Cotai Strip. 

With Las Vegas Sands (LVS -0.92%), Wynn Resorts (WYNN -1.16%), and MGM Resorts (MGM 0.90%) all building resorts, the new hotel tower will not only give Melco Crown a draw to its existing casino -- it will also create even more critical mass on Cotai. Once the majority of construction is completed in 2017, the region will be an even bigger draw than it is today, meaning growing earnings for companies with exposure there.
