Wondering if anyone has booked this and how the credit was issued.

"4th Night Free with Sunsational Savings! Credited at check out, Breakfast for 2 daily @ Restaurant La Villita
No penalty for changes/cancellations until 10/11/2016
No deposit required"

I'd like to book this through Citi Prestige concierge for 4th night free. If Sheraton credits the full 4th night, it will be redundant. If they credit 25% or whatever, then it will be awesome.

Any data points?
