Hotel built with 200,000 plastic cards. Well if that is not surprising, since it is one of those hotels very strange as far as construction is concerned. The Holiday Inn Key Card Hotel was built by card-stacking master Bryan Berg, from 200,000 discarded hotel key cards. To mark the relaunch of their hotel chain, numbering 1,200 establishments, Holiday Inn inaugurated
the world’s first key card hotel, in Manhattan, New York. It’s made up of a guestroom, bathroom and lobby, featuring life size furniture made-out of key cards.
