One tip I would give to anyone thinking about camping with kids is to bring messy art projects!
My kids especially love art. Every day they color, draw, paint or just make a mess, EVERY DAY! They love it!
Right before we left I found this one online. It is painting with a clothes pin and a cotton ball. I had them do this a couple of times. This time was on paper. They also did it on rocks and sticks.
