My camping buddy has that exact tent for himself and 2 kids and still has ample room. I myself have the 8 person Coleman Instant Tent and it has been fantastic. Got to camp at 1:30 in the morning, had it up in under 5 minutes. For car camping it has been fantastic. I'd recommend the rainfly, we got sleet and some snow up in the Yosemite high country and got a tiny bit wet inside (without the fly).
My wife and I love our Coleman 8 person pop-up tent. We also got the optional rainfly with it as well. As far as seams, we always treat the seams of a new tent and retreat after a few years. We will also spray an extra layer of rain repellent just to ensure the the tent is completely dry. I always find the included bad to be too small so I bought a larger duffel on wheels for it.
Any tent you get, also get a ground tarp. If it is larger than the tent, tuck it in, its there mostly to protect the floor of your tent.
My wife and I like this Coleman tent so much that, when mice chewed up the tent in storage, we bought another one. They sell a additional tarp that fits the top, I highly recommend that as well. What's nice about this tent is that you can use it as one big 8 man tent or, like us, split the areas into sleeping and screened porch area. And the front door can be unzipped for HUGE access. It has a door on the back as well.
This is also a pop up tent so very quick to setup and put down. Always get yourself a ground tarp. This is not for water but to protect the floor of the tent.
For the love of Larry, Avoid the 14' x 10' version of this tent unless you want a disposable halfway through the burn. The smaller 4 person and the even smaller 3p version is a pretty decent and easy set up tent that has lasted several burns.
the 14x10 sounds great! It's got front and back doors, perfect for a van or to chain together sorta, it's got stuff for a separate room..
It's NOT a stable design. The spider at the top (think the top of an umbrella where the spokes meet) is basically made of cottage cheese, tinfoil and anti-playa, which when met with actual playa, gets annihilated. The spider and the legs just can't handle any force at that size, and instead of actual bolts to bolt the paper thin recycled metal of the legs into, they have weird screws made of the shittiest recycled metal imaginable. It's like like a lead foam. I could easily bite through it. It's so bad, you can't even improve it. Also, they cheaped out at the top of the sealable zipper windows by making it always open. (?!!?) at the top and the top vent is also always fully open, unlike the smaller version, so a light breeze blows playa rrrriiiighttt up the side and dumps in. All the zippers jammed regularly in ones both on playa and ones never on playa. Lubrication helped very little. Poor sewing and a garbage fake ykk lookalike zipper.
I've had 3 of these bastards die on playa under basic wind, nothing much.. 2 at home on nice simple boring safe camp trips. The 14x10 is truly the shitty umbrella that didn't have to be shitty.
Here's a link so you avoid it.

You HAVE to use the tie downs. And more than they provide if faced with any 10mph + wind. And reinforce the legs with conduit or better. totally negating the instant up feature. This thing was built to try to die as fast as possible. I grew up knowing a coleman tent designer... he would have never made something this bad.
Interesting. Both of my go-to car camping tents are Coleman.
I think the latter is the one you're referring to. Both are excellent.
