Ok, since this was posted in October, I hope things have been resolved by now, Semiruralgirl. What has been decided?
IMO, your SS (stepson) was a little out-of-line to just tell you and DH that he and his family are coming to spend Xmas with you for a week. They have a right to come home to the UK whenever they wish, of course, but they should have asked you and DH if they could stay w/ you or if it would be better if they found their own accommodations nearby. But what's done is done, I suppose.
I'm glad that DH is discussing it w/ you and didn't just say, "Great! We'd love to have you!" I just hope he let SS know that he had to talk it over w/ you before making definite plans.
I realize he's excited to see his DS (dear son) and family at Xmas, but since you're involved w/ them for the whole month of July, IMO, DH should understand that you might not want to host them for a whole week at Xmastime, as well.
Regardless, I agree w/ those who say you should spend at least part of that time away from your home w/ your own DS. etc. It's understandable that DH is eager to have his son there at Xmas, but then, let him be ready and willing to do the hosting. This visit may well set a precedent for the future, so, IMO, you need DH, SS, and family to see that you won't be at their beck and call at this time of year as you are in July.
But chances are, the decisions have already been made. So please let us know what's happening...
