I'd like to be able to use the Marriott anniversary free-night before it expires but I won't be able to. Are there any ways to extend the expiration? Would I be able to book the night, before it expires, to a later date--about 4 months later? I am trying to find a post I read several months ago that said, if I recall, that someone called Chase and asked for the expiration to be extended and it worked...I think.
