I hear you on those road trips I remember sitting in back of a station wagon with my brother playing WAR (52 playing deck of cards game) from Cincinnati ohio to flordia as a kid. We did rest stops not hotels. When we got older and parents had 2 more kids middle seat of van came out and a potty chair went in that was fun. Stinky van.There are some great State Parks out there and some with camping and bathrooms. I used to take my kids 2 at a time on different weekends and stay at a State Park. We were poorer then and we'd sleep in the van. Being small I packed so with all the seats out we could pack everything in two coolers and still have room to sleep inside. Sterno stove and one pan. Instant coffee and creamer had to do. Untangled lots of fishing line in those days. No portable VCR's in those days so they had to read by flash light. It was fun.
Any chickens/chicks should be fine for the one night as long as they have clean water and food.
I wouldn't mind a state park camping I don't know ny at all so will have to look them up when a place and date is picked for the picnic.
