tiger, no, they haven't got the money in the sense that the "family" holiday to Cyprus literally can't happen - I've discussed it with him a few times because he's okay with it now but it did take a while.
in the other cases, again, the "family holiday" got put on hold for a few years. Yes, the childcare is paid for if someone is actually doing it but I just mean the actual cost of the holiday, which I thought was your main concern. Apologies if I got that wrong.
if you mean holiday + additional childcare needed because he can't cover - again, if he can find the money - and my friends aren't rich, they planned this for what feels like decades! - then it's different.
I just got the impression you were more annoyed by the fact that he was getting a holiday and there wouldn't be a family holiday as a result, and I'm just thinking that perhaps for him, one year of seeing a close friend would be worth that. But note, I am expecting him to cover all costs!!
I also don't what your agreements are re one person being left with 4 DC - as my mate in the Cyprus/Vegas situation is the SAH and his wife works long hours, he doesn't feel it makes much odds either way.
