If opening day was any indication, it's a pretty sure bet Maryland's brand-new $1.4 billion integrated resort casino — billed as "Las Vegas on the Potomac" — is going to be a winner.

"They could not admit any more people until other guests left" on the first night, Liz Fitzsimmons, managing director of the Maryland Division of Tourism, Film and the Arts, told CNBC. "And they have been at capacity several days and evenings since then."
