Fifty Shades of Grey Tops List of Books Left Behind at Hotels

While "Fifty Shades of Grey" may be the most bought book recently as it tops best seller lists for months, it is also the book that people leave behind the most at hotels. "Fifty Shades of Grey" is just one of the many top books that guests leave behind when they check out of hotels.

According to a new surveryby Travelodge, a hotel chain in the UK, the book that is being called "mommy porn" is the book that people leave behind most often at hotels. Travelodge notes that 7,000 copies of "Fifty Shades of Grey" were left behind at their hotels since the book came out. A possible reason behind this is the fact that the book is so popular in recent months as it, along with its sequels, have taken over the top of book bestseller lists as curious readers desire to know what happens in the erotic novel that women are raving about. Due to how well it sells, there are more copies out there to be left behind.

The series sequels, "Fifty Shaes Freed" and "Fifty Shades Darker" also make the list of books left behind. "Fifty Shades of Grey" wasn't the only book left behind though. Travelodge found 21,786 books left behind in their 36,500 hotel rooms.

Stieg Larssson's "The Girl With the Dragon Tattoo" and its sequels also dominate the listof books left behind as these books are also very popular among travelers.

The survey also noted some fun finds. An elderly couple left a bag full of Karma Sutra books at one of the hotels. People even left their e-readers at some hotels. A CEO left a suitcase full of comic books.

Here are the rest of the top 10 books let behind at hotels according to the Travelodge U.K. survey:

2. "The Girl With the Dragon Tattoo," by Stieg Larsson
3. "The Girl Who Kicked The Hornets' Nest," by Stieg Larsson

"Fifty Shades of Grey" has played a larger role in hotels than just being left behind. In July, the owner of the Damson Dene Hotel in Cumbria decided to replace all of the Gideon Bibles in the hotel room with copies of "Fifty Shades of Grey." Several hotels across the United States now offer special "Fifty Shades" packages.
