To go on holiday without DSS

[Thestreets]

We had planned to go on holiday for two weeks at the end of August/beginning of September as the kids were due back on the Monday. Now my DSS school has informed us they are to return on the Thursday so he will miss 2 days of school. He is 15.

His mum will absolutely not agree to missing two days of school - I personally think its a drop in the ocean when he has missed 4 months! My problem is DH will not go for less than 2 weeks as this may be our last holiday for two years for various reasons. We cannot go any earlier in the month.

AIBU to say we should go for 10 days then DSS can come with us? Or is DH right as he feels DSS mum is just putting another obstacle in our way (there is a long history)

For context I have DS 14 and DD7, me and DH have been together 10 years and I feel if we go without him he will feel pushed out which is something we have tried really hard not to happen as it so often does with blended families.

YANBU - go for ten days take DSS with you
YABU - go without DSS and fir 14 days as planned

I'm usually the first one to support term time holidays but not in year 11 and not after this long of a forced break. He's going to miss those first couple of days being back with his mates, rendering friendships, getting his timetable, ironing out the wrinkles etc. It's all been difficult enough I don't think missing those first few days would be helpful socially or educationally. I wouldn't allow it either.

And it's two days! Miss the two days so he can come, it's not that big of a deal.

Fair point, I had old information. Seems options to send him home alone will be very limited.
