The tent may not be the cheapest of camping options, at almost two grand, but it does sleep 16 people and can hold 72 people standing for parties, so if you all club together becomes more affordable.
Firebox have a video on the site on the tent being put together and apparently takes less time than it takes to get to Morden from High Barnet.
Features include
7 zip-separated compartments
2 side doors and a drivers door
Doors open, just like on the original
Fly sheet doors separate inner compartments
For the "authentic commuter experience" you can "share your tent with 71 strangers". It's also pointed out that "You can even get in through the drivers door! A rare treat."
"The magic, mystery & sometimes maddening shortcomings of London's Tube are documented with love, enthusiasm & sometimes despair by its unofficial social historian." The Guardian
