AI definitely worked for us at this stage. But it IS expensive. And done brilliantly, it is eye-watering. So when it seems unappreciated, it is hard not to resent the spend. So we experimented with not making it too spendy too.
With UK s/c holidays we found giving everyone their own room made a big difference. Upped the cost but made everything easier.
Wrote off mornings. AI - left them in bed, had quiet breakfasts with DH. S/C - left cereal/toast/fruit/pastries and went out for a coffee/breakfast/brunch/walk/potter with DH. Or, occasionally, by myself.
Food was all important. Easy when it’s spectacular AI but made some space in the s/c budget to allow for some good pubs, nice places to eat, among some (admittedly crowd pleasing) self catering. Filled a cupboard with snacks they could help themselves to at any point. Saved Nectar points all year for a trolley dash of guilt-free joy…
Also suggested one or two new experiences. Didn’t fanfare/pressure. What I thought they would go for they didn’t, what I thought they would eschew, they loved. Though perhaps including good food as part of the latter experience helped too…
Didn’t insist on them joining in for board games, cards, reading books, movies. Didn’t make a big deal when they occasionally joined in, didn’t comment when they didn’t.
Mine were especially fond of a hot tub - we had some good chats under the stars and it felt special and different to the usual routine.
A log fire late at night was also good for this - whether in a cottage or camping.
Teens are hyper conscious of what their mates are doing. And sometimes I knew they felt the poor relation and at other times they realised they were the lucky ones and having a holiday others were not. Hopefully, experiencing a full range of holidays with their family will be what they remember. Looking back at the last holiday photos, which was difficult for multiple reasons beyond them being difficult ages/stages, I see a lot of happiness.
Good luck. It’s not easy, straightforward or what any of us expect. And quietly planning epic solo fantasy holidays is a perfectly reasonable (and efficient!) therapeutic response when they are being a pain…
