"If you're planning an event at one of the Dorchester hotels, please host it elsewhere," the ad reads. "If you're going out for drinks or a meal, dine at a property whose owner doesn't support the oppression of women and LGBT people. And please don't spend a night at any of the Sultan's Dorchester Collection of hotels."
Aside from the previously mentioned groups, the HRC, the National Gay and Lesbian Task Force, Equality California, the Feminist Majority, the Latino Equality Alliance, and the UniteHere! Local 11 union helped pay for the ad.
