We did a lot of self catering holidays (we enjoy those anyway- just the chance to slow down!). But places where we could get out and do things together.
Centre parcs in both UK and Europe, and a french campsite with on-site sailing school, where again we were mostly self catering but had various activities most days, lots of swimming, eating out a good bit (an average of 1 meal/day in CO, abd every 2 days in France as not so many options). But dd loved the sailing (she was about 11 then, and had already done a few levels at home but they started at beginners).
When she was 14, we started going to world championships for her class in sailing, went to 2 before Covid hit. But they were our holidays, as there was a tour tacked on to 1 (far east) and we added a week of our own to the 1 in Europe.
Since Covid, she's moved more into hockey, away from sailing, so in 2022, she was 16 and we left her at the airport after the flight to go to a hockey camp while DH and I went for a weeklong city break (it's what she really wanted to do) and we met at the airport for the return flight. Last year, we dropped her at the airport on this side (loads of people go there and the system was very well organised for kids travelling solo and she knew someone else going last year so met them at the airport here) to do the same coaching camp.
She didn't always make friends, but was happy to have fun with us, do some silly things together, and get out to enjoy different adventures on various holidays.
She really loved the year we went to Florida (thanks to an unexpected bonus), we did Disney but also Cape Canaveral and a canoeing trip seeing a lot of local wildlife (flamingos, turltles and crocodiles) before going swimming in the creek.
The sailing trips were great as she knew lots of the participants from our club and national circuit, and from previous events.
She also really liked the year our big holiday was a ski trip.
We had planned to do a Neilsons type holiday with a lot of sailing (I'd get certified and DH do basics week 1, and charter flotilla week 2 with DD likely the effective skipper!), but Covid hit and she was gone beyond wanting family holidays at the end.
We found she never really took to kids club. She wanted to be with us - swimming, cycling, walking, cooking together... She loved being allowed go to the shop alone in Centre Parcs, which built her up for greater independence at home the following year. She would do some culture (museums, galleries etc) but somewhat limited. She was also happy to relax with a movie and us all together as we never got time for that, or a night of card games or board games, at home.
