and the integral role of natural greenery in the park's appearance prevented the opening of the park year-round. In 2010, Efteling announced plans to remain open year-round. From November through about February, the 'Winter Efteling' theme remains in place. However, attractions that involve water, such as the rapids ride 'Piraña' or the water coaster 'Vliegende Hollander' (Flying Dutchman), are closed. Gisela Williams, a reporter for The Wall Street Journal, wrote a review of the park in early 2014. Williams praised Efteling but criticized the teacups-style ride Monsieur Cannibale due to ethnic stereotypes. Her review was later mentioned in De Telegraaf, a daily newspaper in the Netherlands, and drew several angry comments from its readership. Williams also received her first death threat for her comments about the controversial attraction. In recent years, activists have repeatedly requested the Efteling to remove or re-theme the attraction. In June 2021, the park closed the ride for an extensive renovation including a re-theme. The park received its 123,456,789th guest on June 19, 2015. The Efteling opened the trackless darkride Symbolica in 2017. With a price tag of 35 million euros, it is the most expensive investment in Efteling history. Beside the theme park, the Efteling operates two hotels, a theatre, a golf course, and two holiday villages. The Efteling inaugurated its 30th fairytale in 2019. In December 2020, the park was forced to close in compliance with the new COVID-19 restrictions introduced by prime minister Mark Rutte and the third Rutte cabinet. Design The success of Efteling has been attributed largely to its ride designs, architecture and atmosphere. When Anton Pieck was asked to design the initial fairy tales for the Efteling, he made sure the park would live up to his personal high standards. There would be no use of cheap building materials, plastic, or concrete. Pieck's illustration style, somewhat grim and dark, but also romantic and nostalgic, was the thematic base on which nearly all future expansions were built. Pieck worked for Efteling until the mid-1970s, when his position as chief designer was passed on to the younger Ton van de Ven. Van de Ven had already been working for Efteling for several years and Pieck was very pleased with his work. The Haunted Castle (het Spookslot), which opened in 1978 as the park's first new large attraction, was Efteling's first to be designed entirely by Van de Ven. Van de Ven continued
