Trim your company's travel expenses by staying at a budget motel. In 1982, the average rate for a hotel room was about $58; a motel room averaged about $39. Choosing budget motels is a growing trend among business travelers. Motel-industry analysts expect business travelers to generate at least 52% of the budget motels' 1983 sales, up from 44% in 1980.

A just-released Economy Motel Guide alphabetically lists, by state and city, 2,800 motels in the United States and Canada that cost $15 to $35 a night. All of the motels listed offer air-conditioning and television, and many also feature swimming pools and restaurants.
