"Despite efforts like 'lost and found' boxes, some hotel staff have gone to the extreme to reunite guests with their possessions," said the report.

Hotels.com dubbed some workers "hotel hero[es]" with one driving 100 miles to return a passport, another running several blocks to deliver items before a cruise ship departed and one shopping to replace a lost teddy bear for a young traveler. 

The oddest room service requests consisted of an Evian-filled bathtub, 4 pounds of bananas and a caviar hot dog.

"At Hotels.com we know hotels inside and out – it's in our name. By asking hotels to reveal the secrets behind their most memorable stays, we discovered that these 'innsights' have actually inspired services available to guests today," Melanie Fish, vice president of global public relations at Hotels.com, said in the press release attached to the report.

The company also revealed the most common items left behind by hotel guests.
