If you’ve ever wondered what to do with unwanted hotel key cards, then think no more.
Because, providing you”ve somehow amassed 200,000 plastic slips, the solution is simple – use them to build your own guest house.
That, at least, is what one hotel chain decided to do.
Holiday Inn’s Key Card Hotel, which opened today in New York, includes a guest bedroom, bathroom and lobby, all fully equipped with life-sized furniture all made out of, yes, well, you get the point.
The 400 sq ft, two-ton construction in Manhattan , which will be in business until September 21, was built by world record-holding 'card-stacker' Bryan Berg.
He said: ‘This is my largest card-stacking challenge to date and the only card creation I have ever made at full human scale.’
During the five day event, Mr Berg will build a freestanding 9ft replica of New York’s Empire State Building in the lobby using Holiday Inn playing cards.
It marks the relaunch of the chains 1,200 hotels around the world.
Kevin Kowalski, senior vice president of global brand management at Holiday Inn, said:
‘The Key Card Hotel is a fun and interactive way to showcase the changes happening at our hotels and is the only structure of its kind to ever be created by a hotel brand.’
Mr Berg first broke the world record for World's Tallest House of Freestanding Playing Cards in 1992 at the age of 17, with a tower 14ft 6in.
Since then, he has been commissioned to break his own record ten times.
His most recent tallest record was a 25ft 9in inch tall tower built at the African-American Museum at Dallas, Texas.
For this record, he tried a new technique involving stacking cards vertically instead of horizontally, which reduced the number of cards needed by nearly half.
In 2004, Guinness created a new record category for World's Largest House of Freestanding Playing Cards to recognize a project Mr Berg built for a replica or Cinderella’s Castle for Walt Disney World in Florida.
