I clicked on this thread as I am considering something similar.
I have always wanted to visit a certain place and have been looking (for over 10 years!) at a particular holiday which involves staying with locals. I know DD wouldn't cope with this as she takes a few days of being an absolute horror, to settle into a change of scenery. For this reason, we have invested in a caravan that has all her familiar stuff in, to help her.
We will tour France in the caravan during the summer, and I know she will have a wonderful time.
However, I'd like to do the other holiday in October, without her. It's for a landmark birthday (mine), and I would love DH and the two boys to be with me (I'd actually love DD to be with me if I thought she'd cope... but I know she wouldn't).
I was going to pay for my parents to take her to CenterParcs while we were away. She loves it there and its familiar.
The other holiday just costs too much, and I've wanted to do it for such a long time. The rest of the family would get a lot out of it, but I don't believe that DD would (DD is 17 and has M/SLD and other issues).
Reading the thread though, I think I should maybe forget it
.
Ironically, I agree with the majority (although I think some of the comments have been really unkind), that this is a child who is acting out because she feels set apart to a certain extent. I can identify with that, as I was the eldest, from a different relationship. I was left out of holidays as a 'difficult' teen (the excuse was that I was going on holidays of my own, with my friends). If I'm honest, it didn't bother me too much (a little), but I was much older than the OP's DD.
