I came to realize this week that you don't get free breakfast as your elite status when I stayed at Courtyard Bellevue, WA. I called Customer Service reps to confirm and he said only if there is Executive lounge, then you will get free access and it serves breakfast and evening snacks. However it doesn't match what Marriott platinum elite benefits guarantee states online. I am enclosing a snapshot and following URL of the same for reference. As per the site, we should be eligible for compensation
