I think that you could take all the responses in this thread, and make an assumption of what your buddies thoughts on you bringing her would be lol. I have a 6 year old girl that will eventually go to hunting camp with me, we did a family antelope hunt last week and I know she'll end up going to elk camp in the future. Also, you know your kids and your buddies best, so you can probably estimate how it will go if you're honest with yourself and I assume you are only trying to get a second opinion and get some affirmation that taking her is the right idea.
There are only a couple things to me that would make it a no go for some of your buddies,
1. If they are early 20's, they may not be "mature" or in other words like to be hammered and being ridiculous and a kid would hamper that, but you are likely not in a camp with that because you have a 12 year old and after having kids we're just too tired to do that kind of thing anymore.
2. Your kid is a brat and that kind of attitude would be real annoying in camp if you are constantly bickering with her about being outside, doing camp chores, being cold, etc. etc. Bickering with a sibling, wouldn't bother me because I think that those kinds of fights can be funny because at that age they are usually about unserious things, but with a dad I don't like it. If I were at camp and this was going on I'd be annoyed mostly with you for allowing that to happen. I wouldn't likely say anything unless she was specifically rude to me or unsafe since there are guns in hunting camp, but I may rethink the next year on if I would attend or not. But I would never deter someone to take their kids and they would likely work through it all with time.
Now my experience growing up, though I was not a 12 year old girl, my dad took me to all hunting/fishing camps, to the point we might have been butting up against truancy laws. He later told me that some of his buddies were not super pleased with it at the beginning but he just told them that he's taking me and that's the end of the conversation, and since he was the one that actually knew how to hunt/fish and put the trips together, if they wanted to go they had to be ok with that. He would take me to our hunting club in Alabama that was anything but kid friendly, mid 90's stacks of playboys by the toilet, a weird portrait of a naked woman in the living room, lots of drinking that would get out of hand (he shielded me from that for the most part, and he was a pretty big guy and I'm pretty sure that he had some tumultuous conversations with some guys about their behavior). Those are the things that we didn't talk to mom about haha. But it was a great experience and I wouldn't trade it for anything.
In the end, I think you know what you want to do and you'll end up taking her, because If you are anything like me, if there is anything going on in camp that is truly despicable enough that kids shouldn't be around, I wouldn't want to be in the camp either.
