By collaborating with Canyon Ranch, a pioneer in the destination health industry, Las Vegas Sands hopes to increase its chances of winning one of the three New York downstate casino licenses. In previous discussions of the multibillion-dollar project, representatives from Sands have also hinted at a comprehensive day spa and fitness center. This week's revelation of Canyon Ranch's involvement in the project made such remarks more understandable. In what is expected to be a fiercely competitive bidding war for the three highly sought-after concessions, Sands is one of about a dozen casino proposals that are now being developed.
