Hightower Mansion 8 Person Tent

I have the Hightower Mansion 8P and it's great, very easy to set up and doesn't take up a lot of room in the car (half the length of the coleman instant). Assuming it's something you'll use a few times I'd recommend the 8P over the 6P as it gives you 2 separate rooms which might be better for when the kids are a bit older.

The Walmart Ozark Trail tents are decent. You won’t get a big one for under $100, but I got our 8 person tent for like $120 I think. I am short so I can stand in it almost straight up.
