In the course of my travels, I’ve seen all kinds of hotel and hostel promotional giveaways and handouts. The typical items are postcards, imprinted pens, local maps and even branded bottles of water, but the Kokopelli Backpacker Hostel has topped them all. To encourage guests to visit their new location in Cuzco, Peru, the Lima-based hostel has begun distributing business cards with coca leaf-shaped cut-outs. Travelers are encouraged to pop-out the coca-infused leaves and to chew on them to alleviate altitude sickness when they arrive in Cuzco, which sits at 11,152 feet above sea level.
