The 400-Square-Foot Key Card Hotel

Here Berg unveils his 400-square-foot Key Card Hotel – made with more than 200,000 Holiday Inn key cards – at the South Street Seaport. The incredible Key Card Hotel features a guest bedroom, bathroom and lobby with life-sized furniture made out of key cards. Berg takes a break on the key card bed. The 34-year-old professional cardstacker has also broken the world record for World’s Tallest House of Freestanding Playing Cards in 1992, and has been commissioned to break his own record a number of times since then.
