Yes. Just happened to me. Unable to book a points stay on line. Called in agent said my account is invalid and unable to book. I made a comment about what a mess the merger is and the response was "well its a big system". Totally unacceptable. Ended the call with no resolution and no suggestion on how to correct. How can this possibly be? So I am flat out not able to book a former SPG property. Marriott should be ashamed.
