Actually I think it boils down to how the woman feels about herself, not how others view her. If my guests blamed me for the lack of preparation for their visit I would think that's their problem, not mine.
Yes, well, if "my" guests blamed me, I think that'd be quite fair - if my parents, friends, whatever come to visit, I would like them to be comfortable, and - if the occasion warranted it - more than comfortable, pampered or celebratory as appropriate. If I have guests, I think it is my responsibility to prepare for them. How this makes me a slave or a control freak is beyond me, honestly.
If DH's guests blamed me, I'd agree in theory that it is nothing to do with me and let him sort it out. Except when you have to actually deal with the MIL, family friend, or stepchild who has judged you and found you lacking, all the positive self-esteem in the world does not necessarily protect one from stress and grief. In the original example, OP could take the view that DSD's comfort and happiness are not her problem, sure - but it won't add to her happy home life, it may well result in problems with her relationship with her DSD, and there will be both short term and long-term repercussions.
(And incidentally - while this is of course of no concern to the lovely ladies here with such high self-esteem and lack of interest in the views of others - it would almost certainly get her a roasting on MN!)
And add to this that guests to my home aren't so easily divisible into "his" and "mine" - if his sister comes to visit, I'd like her to have a lovely visit, a comfy bed, a reservation at a nice restaurant, and to have our childcare and work sorted out so that we can all spend time together. So sure, I can throw up my hands and say "not my problem! It's his sister!" - but this doesn't actually make my life better in any way. It's not unreasonable instead to expect DH to be a bit more organised about plans and communications, which is all the OP is asking for, actually.
