I'll second (or third or fourth) the XWT from Cabela's. No clips, pretty straightforward set up, one sleeve - for the front vestibule, good floor plus a clip in floor liner (option). It also has tons of guy outs and a floor that runs about 6 inches up the side (creating something of a tub) before you get to the sidewall seams. Ventilation is good when needed. The full coverage fly (which also establishes the vestibule) makes it a true 4-season tent.
We have the 12x12 and it comfortably sleeps the five of us (we have three little ones as well) along with room for the dog, a big buddy propane heater and our gear. The design of the tent does an excellent job of shedding wind-load and what's left is easily distributed across the many guy lines. We would go anywhere in this tent (well, it is a bit on the heavy side - comes in around 50 lbs., I think).
If you have time and nearby locations, you might be able to catch this tent in the Bargain Cave at the store. The best time to look is about 2 weeks after the close of major hunting seasons in your area (and particularly in the week or two after Christmas). Many people buy these tents and return them after one hunting trip - particularly around Christmas when the $700 goes a long way towards gifts.
We got ours the week after Christmas a few years ago for more than 50% off (less than $300) - it looked like it had been used for one trip - there was a -very- small hole in the main tent fabric that we easily repaired. Make sure, if you go this route, to take the tent out of the bag and examine every piece and pole of the tent. We examined ours very closely and were told by one of the associates that people rarely do so.
I'd also like to chime in on the Alaknak from Cabela's. As was previously mentioned - this is really a basecamp tent - we have the 12x20 and now use it primarily as a basecamp/community tent when we take our yearly family camping expedition. It has saved our bacon more than once in that regard, allowing us to have a place to sleep, but also room for everyone to congregate and eat in when it is 15 degrees and snowing outside (a few years ago up at Canyonlands N.P. in March). In fact, it weathered a wind-storm when none of the other tents in our group did - we ended up sleeping 14 in it. The downside is that it really needs a wood stove for heating it and we're not comfortable with that around our littles. The no-fly design and wet-burning nature of propane combine to exacerbate condensation problems that we would likely not have had with a wood stove.
Finally, invest in good stakes that are appropriate for your expected conditions and always try to carry a few of each type in the event of the unexpected.
