I only got coupons for Friday morning but I did receive 2 of them which is different vs. 9809JD's reported "member only" experience. Both coupons were dated for Friday and it did not appear that the Gold/Plat breakfast area was even set up on Sat/Sun (it's on a mezzanine level overlooking the lobby).
FWIW there is a Dunkin Donuts next to the hotel (turn right out the front door) and the nearest Starbucks is a block over on 5th between 28th and 29th.
