Both Expedia and Hotels.com are offering a $50 gas card when you book a hotel stay of three nights or more. The offer is valid for travel through Sept. 1 when you book by July 6.
At Hotels.com, it's part of their annual Summer Drive & Save program. But when I tried to use the coupon code (GAS50) for an upcoming trip, I was told it wasn't valid at that particular hotel, which is a Marriott and is my ab-fab fave place to stay. It did work on a Hilton hotel that was more expensive. I was bummed, but not enough to switch hotels.
So I went to Expedia, where the gas card is part of the Summer Adventure sale. This time, I was able to get my hotel choice plus the gas card. Score! The Expedia offer is only good through the end of June and you gotta fill up by Aug. 31.
If you're already planning a trip and use one of these offers, it can pay to stay. But first, make sure you can get your hotel choice and make sure you can't get a better rate at the hotel's Web site or by using an AAA or other membership.
