These are great ideas, think I'm going to copy some of these lists!
I don't know if I'm picky, but I vastly prefer cots (and a sleeping bag) over an inflatable mattress pad. I sleep almost as good on a cot as I do at home; not true with an air mattresses (especially if sharing with 1 or more people). Kids may not be as picky, but there are cheaper low ones for kids. Heavy if hiking in, but fine if you are driving in.
My kids love: campfire songs or stories (especially ones that either happened to you or have to do with area camping), "treasure hunts" where you make a list of things to find, have a prize at the end (could be things that are commonly found, with a couple unusual things thrown in), marshmellow roasting, weenie roasting. Kids LOVE to have their own http://www.robustbuy.com/led-lighting-gadgets-led-flashlights-c-505_1027_730.html or headlamp, so I'd make sure every person had their own with their name on it. If you can, bring guides of: bugs, reptiles/amphibians, birds/plants/trees of the area, so can identify local wildlife you see.
Almost all kids are interested in fishing. Your kids may be too young, but at some point finding bait and doing catch and release is a relaxing low key activity.
I'm surely agree with you. Those are really great ideas and I wanna take some form these. Thanks to the author
