Been there....its not as bad as you think. Assemble the top and bottom squares completely, then assemble each side pole (usually two pieces)....turn bottom square sideways to get through the door and put it in place on the floor, put the side poles in the corner pieces of the bottom square, turn the top square sideways to get it in, place it on top of the four poles and snap in the corners...assembling everything inside the skin of the tent as you go...stuff the bottom square in there, use the side poles to hold everything up, wrestle the top square into place...bam, done.
That sucks the rest of your stuff didn't come in today...fedex is hit or miss sometimes, it seems.
