My son and his family have this Mountain Hardwear Casa 6 Tent @rei.com, and loves it! It is freestanding, easy to put up and take down, has a vestibule, rainfly and many, many other extra's! Great buy for any family!
Why stuff yourself into a tiny pup tent when you have all of the great outdoors to stretch out into! Make room for the sleepers with this tent for six.
