It doesn't really say how many rooms will be given away during the 24 hour periods. I assume there has to be some kind of limit or else they would get thousands of people booking for a dollar, which can't be good for business. Or maybe there's some kind of catch like you get a room for a dollar but have to book another night at full price. Either way $1 rooms sound like a good deal, and it's good to see a struggling property like Sahara get creative with their marketing like this.
