I got mine down a stairways in the box. Even with a "jog" at the top of the stairway. There were three of us. We used an appliance dolly. The trick was we had a "refrigerator" strap and the guy at the top guided it. Two of us at the bottom simply glided it down the stairs.
JJP's website has the instructions for set up posted. We slid it out of the box, no reason to cut the box apart. When you get it up on the legs and ready to go, remember to remove the foam blocks that cushion the playfield. It helps to have a couple friends around when you set it up on the legs, it is heavy.
Enjoy the journey.
