I understand its YOU camp and all, BUT if the folks that been going there haven't HAD to deal with a kid there, and you suddenely bring one
you could cause a issue with some, as they might have come to a understanding of what goes on
altering things SHOULD at least be run by them a head of time so THEY can make the decision if they still wish to come
springing it on them once there there isn't a very nice thing to do IMO

I belong to a hunting camp, and we have had members that showed up pout of the blue with a kid, and it effected a lot of the normal Deer camp pranks, that were more adult orientated and what many came to camp for
heck we have guys that don't even hunt that just show up for the events that happen every yr
and when kids show, up, we all have to adapt
most don't mind(me included I like seeing kids into the sport to be honest)
But some guys don't like it, and some cannot help the four letter words from flying as they slip up here and there, BUT damage is already done at that point? LOL

SO< I still say you should run things by your guest, so they know what they can expect, and allow them time to adjust and or decided if they still wish to show up .
I doubt many would care, but its the heads up some times that matters more
