I had been assured verbally and in writing that these points do not expire ("never expire regardless of usage"), and now they will. They could have just changed the rules going forward, but they changed the rules for miles earned previously. Poof, just gone. Totally unacceptable. I will try very hard not to use any of their hotels going forward. Even if your points are not expiring, you should consider staying with other hotels as well. If they change the rules and cheat us once, they will probably do it again. They are not being very loyal to us, are they?
