15 was the last time I went away with my parents in the parent and child dynamic. Money was tight so it was irregular, there wasn't much moaning though, we were lucky to go anywhere. UK or occasionally France.
It was always fun though - one year we went on a tour of The North and stayed in travel lodges, explored Hadrian's Wall and gradually came back down. Ate a full English every day. We did Derbyshire in a tiny little car that could barely make it up the hills, four of us plus luggage in a metro. Dorset coast with clotted cream and apple pies. Lots of picnics, and car picnics.
When I was 15 we went to Portugal for my first hot holiday. My brother didn't come (uni) so I missed his company - not that I'd have admitted it at the time! I remember being in a bar with my parents and cringing so much 😂.
At 16 I went away with 1 friend on an archaeological dig and that was it, hooked. Self funded from then on with Saturday job money, usually camping or city breaks with friends or digging solo and had the best time. Not exotic, but I loved it.
We have been away with my parents as adults and it's lovely.
Wrt our DC, I suspect they will tag along for as long as we paid for them too. The thought of eldest DDs last family holiday being in 3 years is awful, there's still so much I want to do with them both!
