I haven’t read the whole thread but I’ve experienced some of the same issues as the op.
We are a blended family with four kids between us. When we started dating they were already teenagers, with the youngest being 11 and the oldest 16, at the time.
Over the years we have taken them many places, and seen many things. I won’t list them all, but I can say that some of our trips have been very difficult when trying to get four teens to agree on anything.
I love Rome. So we took 3 of the kids to Rome, followed by Paris, which I don’t love. They did not enjoy Rome, they didn’t enjoy the old buildings, the art, the heat, the walking, the food. They didn’t complain the whole time, but they weren’t happy. They liked seeing the colosseum. That’s about it.
Then we went to Paris. They LOVED it. We took the hop on hop off at the request of the kids, that was smart. It wasn’t as hot, so that was nice too. However, I really wanted to go to the muse d’orsay. That was a horrible experience. One kid liked it and could have stayed all day, the other two sat on benches pouting and complaining about being hungry the whole godamned time. Nothing moved them. They couldn’t have cared less.
We took out daughters to Barcelona and then to Edinburgh. I LOVE Barcelona. They did not. Edinburgh, in March, on the other hand, they loved.
That same trip I took the girls on a walk through the Peak District. One girl pouted and complained the whole time, the other one took to it like a goat. Climbing up and down soggy hills, having a blast.
Ha, and then two summers ago we did a train tour through Italy. With all four of them. Knowing damn well one doesn’t like to walk, we organised a walk through the cinque terre. I don’t know if anyone is familiar with it, but my god, those are some tough paths. Surpringly there wasn’t too much complaining. But there were a lot of blisters because kids NEVER wear the right shoes. In fact, when we travel with the kids I take extra shoes because I know they will use my practical shoes more than their own. Again though, they enjoyed certain aspects of that trip more than the ones I wanted them to enjoy. You get used to it.
They are now all in their 20’s and look back on those trips with fondness. They dont rememebr how horrible they were, they remember the things that matter now, that we were together as a family.
For me though, I found that each trip got easier. I stopped being so rigid about what they needed to appreciate, and let them enjoy it for themselves. You don’t like the gallery? That sucks, but we’re are going to stay a little longer so that the people that do enjoy it can get an experience out of it. Also, they are always hungry, so make sure to feed them before doing anything you want to do or the complaining will ruin the experience.
