The CLC Check Inn Card is one of those deals that seems too good to be true... but it's true.
We've had the card for 3 of the 4 major repairs we've had done to the trucks we've owned and what a money saver! They get their $4.95 and that comes out of the rate you pay- so you pay $45 for a $90 hotel room and that's it. The hotel pays CLC $4.95.
We've had the card for years and I think there was one mischarge- but they contacted me and corrected it before the statement even hit my mail box. I don't remember exactly what it was, but their customer service is IMO very good.
I've never had any problems with them.
When I tell people about it, they never believe me until they finally sign up.
If you have to get a hotel, it's the way to go.
