We book thru Red Roof Inn at around 7x.xx something a night. I found a discount code from a website called retailmenot.com and it is a 20% discount (code: CP536450). I keep finding all kind of discount codes on that http://www.retailmenot.com/
site. I love it. We have two nights before our cruise that we will be staying.
I even found a discount code for our flight thru USA3000. That even saved us $10/pp. They way I look at it ......that is extra money in my pocket and not theirs and it's just like a savings account keep finding the little amounts it eventually adds up to a good amount.
Hope this has helped!
