This policy matches that of Westin Hotels and Resorts which became smoke-free in 2006. Both Westin and Sheraton are owned by Starwood Hotels & Resorts.
Some 8,000 rooms at the hotels will be cleaned, including treatments for air conditioning, walls, rugs, upholstery and hard surfaces.Smoking will also be banned in public areas in the hotels, but there will be a designated outdoor area at each property for guests who smoke.
Both hotel brands expect to be completely free in the U.S and Canada by December 31st.
