My ds first went abroad with school at the age of 13. Dd will no doubt be the same (currently 11). I feel awful to not be able to take them myself. But we can't afford passports for us all let alone pay for the holiday. We always have great holidays in the uk though which they both enjoy.
Well, going overseas doesn't have to cost more than staying in the UK. In fact, it can be quite a bit cheaper sometimes, depending on when/where you go. I find a lot of UK holidays surprisingly expensive though.
Why doesn't your DH want to go abroad?
I'm not sure I agree with either his or your reasoning, tbh. He works and earns the money, yes, but if you're a married couple its YOUR money, not HIS. I would have a problem if my DH always got his way with our holiday destinations and I got no say at all. If you want to go abroad and so do your DC I really feel he should agree to give it a try or agree that he picks the destination one year and you the next. It's only fair IMO.
We have never taken our 2 DD`s abroad, they are 12 & 13. Younger DD went to Paris with the school in September & Older DD is going Germany with the school in June. Never seemed to be able to afford it, even before I split with their dad last year. We go to Hunstanton for a whole week in a caravan as soon as school is out & then for either a long week-end or mid-week break in August. Last year the weeks holiday was at a Haven site at Hopton. We even have a holiday grant to help us out with the cost else we would not be able to afford it! Kids have never really complained, other than to enquire why we have never been abroad, they love the UK seaside holidays!!
