For a one night stay, it's one credit, $25 per person. As to when and where you can use it, we're all reporting different stories from front desk agents, some are told they have to use it the night of check-in, and not for breakfast/day of check-out. Some are told it must be used all in one transaction at a single venue, some are told the credit can be spread around and they will apply the credit later. In my case, I was told it was for breakfast only, must be spent all at once, at Suns Out Buns Out, the Kitchen, Agave, or room service. I always stop at the front desk when checking out anywhere and ask for a printout to ensure correct charges. There were some problems I mentioned in another post, but was able to correct them in person. I strongly recommend checking out in person.
