I don't think rake arguments are the key at this level.

What the room needs is a live game. Something to bring in a constant flow of live tourists - the locals will find their way to your room.

I am going to suggest a mix of sex and prestige not found in the other rooms.

First, prestige:
Have a walled off room with huge glass windows so everyone can see inside, but giving a sense of privacy. Have a LIVE internet feed of the table (perhaps holecards, perhaps not). Advertise the game as a way to win at the worldwide famous game, amaze your friends. Send a super fancy invitation card to out of town players (perhaps some comp, perhaps not). Provide some token after an afternoon's play (I survived the XXX big game hat, or something like that.) Create a special atmosphere. Have really nice chairs and tables in the room.

2nd: sex
Hot waitresses that hit the "big game" often. Big smiles from them - make the players want to go there. Sharp dealers that are all business. Make the players feel like they imagine a visit to the playboy mansion would be like.
