I have nearly 80,000 Choice Hotel points accumulated. Free hotel nights start at about 8000 points (though some are 20K per night.) Yet do they have any "open" rooms in places where I would like to stay ---- or even considering going to? They do not. (It is obviously a rate restriction as I have just booked a room in one of the hotels for our trip to Grand Rapids in May.)
Fortunately there are other options, each 16K points is worth a $50 gift certificate to Target, Best Buy, Amazon, or a bunch of other stores.
