If this had happened 30 years ago--like Harrah's Casino in Cherokee--I think it would be a surer bet. Harrah's Casino in Cherokee draws on Charlotte and Atlanta. There are buses that take old folks to/from Charlotte/Cherokee every day. How the Lumbees play the I-95 card will be outcome determinative. This is NOT a "if you build it, they will come" situation. Cherokee was an exiting tourist destination before the casino was ever built. One option, would be to make the Lumbee Casino the focal point of an enormous outlet mall, i.e., build on a preexisting draw. Sort of a "Come for the bargains, spend the night for the shows at the casino." Just slapping up a casino beside I-95 without giving people another excuse to come is a recipe for failure. Having the casino as part of the largest outlet mall on the East Coast stands a better chance of success. Letting a Trump have anything to do with it guarntees failure.
