Marriott International is partnering with A Woman’s Nation to promote AWN’s The Envelope Please initiative. The program encourages hotel guests to express their gratitude by leaving tips and notes of thanks in designated envelopes labeled for the housekeeping staff.

Founded by Maria Shriver, AWN is a non-profit organization dedicated to ensuring the value of women is recognized and respected at home, in the workplace and as caretakers. The Envelope Please aims to bring attention to guestroom attendants whose efforts are often overlooked.

Marriott International will place signature envelopes in more than 160,000 guestrooms at participating Marriott-managed hotels in the United States and Canada, making it easy for guests to express their gratitude and leave a voluntary gratuity for their room attendants. Marriott has also invited its franchise hotels to participate in this initiative.

“The Envelope Please was born from having conversations with women I’ve met who have taken care of my room during hotel stays,” said Shriver. “Their stories of hard work and perseverance inspired and informed me. They told me that room attendants, who are often the primary breadwinner for their families, are often forgotten when it comes to tipping, unlike other front-of-house employees, since most travelers don’t see them face-to-face. I hope this gratitude initiative will make these women feel seen and validated.”
