We try to live consensually, where we find a way for us all to be happy, rather than by compromise, where at least one person feels like they have given something up.
So yes for us autonomy spills over into all aspects of family life.
"But if you're an autonomous educator, are holiday decisions dictated by your children's wants and desires? "
We'd all discuss a family holiday, and try and find something that we all were happy with. For us life was not dominated by the children's wants any more than it dominated by ours.
Everyone's family is different, but that is what has worked really well for us since we became autonomous-and having done life where parents dictate choices, this way for us, has been a whole lot happier.
You say that your child has "DS has plenty opportunities to go on other outings and holidays that fill his desires (and bore me to tears)"
Then if I were in that situation, I would be discussing with him, that you do 'so and so' to enable him to do these things, and suggest that it could work the other way too-him coming along with you to an adventure holiday enables you to get what you need to recharge your batteries, to carry on doing things with him.
If that way doesn't seem to be working, then I would drop the idea of the adventure holiday-for the time being- and find something different again that you both will enjoy, so you feel like your needs are being met and you don't feel compromised.
All too soon he will have grown up and no longer come with you, he could maybe stay with friends instead-our teens had friends stay here for days/weeks and they have gone to stay with other families round the country too. Our house usually had extra teens in it, seems so empty often now they are not here.
DH doesn't do camping or hostels-so he didn't come to any of the HE gatherings and camps, I went on my own with the children. Then later we'd find time to do some sort of break with him too.
I wouldn't have made him come camping, any more than I would have made the children come on a holiday they didn't really didn't want to either.
Our children are all grown now and dh and I have lots of time to holiday together, doing things that don't interest the children...... and I still go camping without him too!
