Although I love the other tent that we purchased, it is a cozy space. I thought that a little more room might be comfy when were were camping by the car and staying in hotter locations. We are going through the desert! So, I took advantage of a sale at Backcountry.com and purchased this little number.

Marmot Tungsten 4P Tent: 4-Person 3-Season
It goes up just as fast as the baby tent, but has a lot more room!
