I just received this tent and set it up outside (haven't actually slept in it yet). By my measurements, the interior dimensions seem closer to 9'6" x 9'6". It's 10' x10' if you measure from grommet to grommet on the corner straps. Here's a queen-size sleeping bag, 2 kid sacks, and a pack n play mat. Leaves a little room to walk and maybe some for a dog or your actual luggage. The vestibules are pretty large though.
