#1, I'll look up the wag bags. Everything must be packed out, no burying for us.

#2, I've wondered about that. I've got a 10 year old son that I worry about- I'm sure my wife and I would both be fine for the other, but him... And then we have a 4th non-family member, but I'm sure he'd be fine with me holding the tarp.

#3, yeah, bad knees/hips kind of thing. I'm wondering about a small squatting toilet, something like this - https://www.amazon.com/TRIPTIPS-Portable-Folding-Toilet-Camping/dp/B08P535474
