Aloft, Element and Four Points in North America offer a free $40 gas card with a two-night stay booked by July 31 for hotel stays completed by September 15, 2011. The SSBGAS rate code is the same as the Daily Rate. The $40 gas card requires a daily rate $5 to $10 per night more than AAA rate for several hotels I checked.
