Just checked some upcoming reservations. In all cases my "guaranteed" selection of King Bed disappeared so once again I went in and added it to about a half dozen reservations. And one reservation where I used two Chase free night certs, the certs disappeared and it's asking me to order reward certificates. And the Chase certs were not returned to my account. Original confirmation clearly shows the certs and zero points. Web now says it needs 50K points. So another painful call to Marriott......
