Yes, I often but not always stayed in Motel 6s and always found them clean and cheaper and they are justifiably the best of the budget motels. In 2002 we stayed mainly in Days Inn but these had gone up in price by 2006. In the US they also have what they call 'Mom & Pop' motels which are privately owned and always cheaper still. I had heard horror stories about them as they are often a bit dated and can be less than clean but in my experience, they were fine.

We never use chains like Motel 6 unless we absolutely have to. They are soulless and all the feckin same so the Mom and Pop motels are the way to go IMHO
And fewer miles per day as well.
