A Canadian brother and sister are passing Halloween night curled up in red velvet coffins in the Transylvanian castle that inspired the Dracula legend, the first time in 70 years anyone has spent the night in the gothic fortress, after they bested 88,000 people who entered a competition hosted by Airbnb to get the chance to dine and sleep at the castle in Romania. Tami Varma and her brother Robin, are the grandchildren of Devendra Varma, a scholar of English gothic tales and an expert in vampire lore.
