Looking for other peoples opinions really, I have a DS from a previous relationship, he's 17, I also have a 9 yo with current partner so they're not exactly small children.
Partner wants us to go away for a few days (Thursday-Monday morn/afternoon), to somewhere in the uk, they'll be at college and school most of the time except the weekend. DS1 is sort of sensible but he does have ADHD, they get along fairly well although do have the odd bicker here and there. BIL doesn't live that fair away and has said they can go to his for their dinner but it isn't possible for them to stay due to space etc.
WIBU?
