I have free night certificates good for "Category 4" and "Category 5" hotels. When I tried to use them for a hotel clearly marked on the web page as "Category 4" I learned that the certificates are now only worth 20K or 25K points and that a free night (at this bottom level hotel) now costs 25K points. I guess our Category 4 free-night certificates have been downgraded to a Category 3 hotels (which can be gotten for <20K points). Of course, the Category 5 certificate now only buys what shows online at a Category 4 hotel. The other thing which seems to be changing is that category numbers for most all the hotels I go to are rising higher and higher. So existing certificates are less valuable and the costs are rising! So much for loyalty..
