Car camping in reasonable weather, Coleman and Kelty are good too. I usually put a heavier weight drop cloth under the tent and a cheapo furniture mat/pad down first. You want to avoid moisture or twigs etc poking through.
Vestibules are nice but not a make or break.
It's never too soon to inculcate the habit of never taking or keeping unattended "smellables" into the tent for ALL members of your family. Lipstick, chap stick, candy, chips, cookies, candy chips, cookies, toothpaste, deodorant, perfume, chips, cookies, candy, in other words anything that a four, six, eight or more legged critter might smell and decide to take a bite to see if it tastes as good as it smells.
Mice, rats, ground squirrels and chipmunks, usually can't get in unless somebody leaves the zippers unzipped. Raccoons, skunks, bears, etc, usually open the tent in their own manner.
