Successfully receiving the 500 points for Plts's is the thing that troubles me. The FD clerk will hand me the amenity card, I ask for the points instead and am told that it will be done. More than 50 percent of the time it isn't. I keep a record of these shortfalls and after accumulating four or five, call customer service and they are posted immediately. I don't understand why Marriott can't get it corrcet the first time.
