Hotel chain Marriott International Inc. will announce on Wednesday that it is banning smoking in all rooms of its 2,300-plus hotels in the United States and Canada, the Wall Street Journal reported on its Web site on Wednesday.

The move is part of an effort to stop an increasingly common source of guest complaints, the report said.

More than 90 percent of Marriott’s hotel rooms in the United States and Canada are already nonsmoking, but smoking will now be banned in public spaces, such as restaurants, bars and meeting rooms, the report said.

The change in policy will start in September, and guests who smoke in hotel rooms face a clean-up fee ranging from $200 to $300, according to the story.

A spokeswoman for Marriott was not immediately available to comment.
