I would suggest you look at Eureka brand tents. My scout troop is using Eureka tents that are going on 20 years old. We love them.
Buy two tents. One for adults and one for kids, you'll thank me later. Get identical tents and then as parts break in the future you can canibalize from one to the other. A ground cloth will extend the life of the tent by protecting the floor and a mat (think welcome mat) just outside the door. Make (and enforce) a rule of absolutly NO food/drink inside and NO shoes worn inside, especially with kids. State park wildlife will sniff out the smallest crumb of food and chew through a tent to get it and shoes (on kids) destroy a tent floor.
Remember when shopping to ignore the ratings for number of people as the picture shows on the box, they are stacked inside like cordwood. We have a three person tent that barely has room for my petite wife and skinny me, often times I sleep outside in my bivy bag under the stars.
Got a solid decade out of our Eureka Timberline (A-frame) tent and it would have lasted another decade but I loned it to my brother in law who pitched it too close to a fire.
I appreciate all the info! A buddy gave me an old Sears tent to try out. It's got a canvas floor, aluminum rods and some type of thick heavy material for the walls and ceiling. It's really heavy though and time consuming to put up. I think it would be great for several day camping trips but we're going to look into the suggestions ya'll have listed for overnighters.
Thanks again!
For fun and giggles, and good "dry run" you might set it up in the backyard and have a campout with the kids one Saturday night. Include cooking a meal or two outside. You'll be amazed at how much stuff you will find out you don't need. That way if you forget something you're still at home and not 60 miles away.
My kids loved making hobo meals (foil packs). Just slice up some veggies (taters, onions, carrots) and put them in a foil pack with about 4oz of burger. Seal it up real good and just lay it right on the coals, about 10 mins each side. Season with salt and pepper and a squirt of BBQ sauce and you have a meal fit for a king...plus the kids get to make their own.
