From your first post, I took it to mean she gave you the discount for every night of your stay. But she did not, but gave you the discount for the nights that were available. She took the time to check nights separately & apply it to them, which is great. That’s very different from saying she just gave you the discount because you called. But it is exactly like I said, the discount has to be available to book it. It was not available for your last 2 nights, and you did not get a discount for the nights it wasn’t available. When I’m looking for discounts, I look for individual nights, or different lengths of stays myself. You saved your self the work by calling. But my point is, you didn’t get a discount that wasn’t available just because you had a room booked already & called.
