Hi Brad -
Several things.
I never could get the thing set up so that the tub would stay rectangular and flat. Best I could do was throw heavy things in the corners, I could not replicate the pretty pictures on the web site.
The high spot is centered, head to foot. This means that laying down, the ceiling is very close overhead and it feels confining. It also means that to sit up, you've got to scoot "south" to the middle of the tent first else you're likely to contact the inside of the tent soaking yourself with whatever condensation has gathered.
The last night I used it there was a pretty decent breeze, not storm winds, just a cold wind coming off the snow and over the little duck-pond sized lake. I pulled the stakes inward and lowered the sides essentially to ground level but there was still too much breeze coming through, got mighty chilly.
