For plats at the Scottsdale Marriott Suites Old Town you get a full free breakfast buffet or (and this is unique as far as I can tell--I've never seen it at ANY other property) you can order anything you want off of the room service breakfast menu as well. Given that I often depart early in the morning and room service is available 30 minutes before the restaurant opens, I've taken advantage of that perk quite a few times.
