(Undated)  --  A California woman is suing Marriott, claiming she was discriminated against because of her race before checking into her Portland hotel room.  Felicia Gonzales filed a lawsuit Monday against the hotel giant alleging the front desk clerk at the Residence Inn by Marriott Portland Downtown/Convention Center told her that all guests had to sign a "no party policy."  According to reports, Gonzales later learned that "protocol" was false after witnessing white guests check-in after her without signing the form.  The 51-year-old is seeking 300-thousand dollars for embarrassment, frustration, humiliation and "feelings of racial stigmatization."  A Marriott spokesman said the company doesn't comment on pending lawsuits.
