The room fee goes to MP, sort of like a cover charge at a club, not the entire total... it's one of the many bylaw rules and regulations that they must abide by (incl but not limited too: display of rates, advertising, services, etc...). not to mention the law. Take a look at the Canadian Criminal Code, and the respective city's by-laws. Tipping is completely up to you. The girl already gets the fee discussed in the rates displayed.
