@David-and-Annie0 This mix-up with the smart-pricing, coupled with IB has really snowballed into a difficult scenario for you. It's a tricky situation- you are either going to have to decline, which will affect your acceptance rate, accept either with or without (if they are willing), discounts, and decide what to do about the "bitter" woman who now is willing to pay full price. Rough.
I'd be inclined to agree on a slight discount for the ones who are asking, as a way to make up for your confusion and mis-steps as new hosts. After all, you have unnecessarily (from their side) used up some of their time, as well. But I'd dialogue with them enough to get a feeling if they are going to hold it all against you and make it clear that you're agreeing to a discount because you were at fault in the first place and want to make things right.
The one who is amenable to paying full price but was bitter- only you can judge whether she'll continue to be bitter and hold it against you, or let bygones be bygones. We haven't seen her messages, so can't judge that. I know people who can get incredibly mad about something, but then just let it go, even laughing it off, and others who hold a grudge forever. I'd be inclined to be perfectly honest with her- that you'd be happy to accept her reservation now that you have your pricing set up right, but that you need to feel confident that she won't hold your novice mistake against you, and be willing to "start over" with you, with no hard feelings, so that her stay will be pleasant for both of you and the subsequent reviews, from both sides, will only deal with the actual stay, not the previous mix-up and exchanges about that. In other words, is she willing to forgive you and move on, without it coloring your future interactions? Then make a decision based on her response to that.
If you do accept her reservation, I'd make sure to leave her a bottle of wine, some chocolates or nice pastries, and a card thanking her for forgiving your newbie mistakes and being willing to rebook, along with the usual "make sure to let us know if you need anything or there's any issues in the house".
