Autism

So, I'm heading camping tomarrow. I've done this before, but tenting is really... out in the open. Any recommendations for sensory management in the outdoors that people have? It's going to be hot, and I'm going to be around more people then normal, and my goal is to reduce the usual 1-2 meltdowns to maybe just 0-1. (I've been getting better, a few years ago we aveaged (3-4). It's a very verbal family. Someone will yell at someone by the end of the week, I'm just trying to make sure it's not me. Things I'm already bringing: Sound Canceling Headphones, Bone Conducting Headphones for my background soundtrack, and enough special interest to keep me occupied for the week. (I have a friend who wants a raspberry pi on his helmet, and I'm going to work out how to do the software will almost no cell coverage... sounds interesting to me.) Has anyone else done something like this before, and any recommendation. (Additional Context: Likely about 22 other family members will be there, it's not quite a reunion, but it sorta is.)
