Crystal Cruises has tapped award-winning international authors on Asian culture and a chef with global passions to join guests and add their regional insights to several compelling tours in Vietnam, India and Thailand.

On select April cruises, Crystal guests have the unusual opportunity to explore Vietnam's mysterious Cu Chi Tunnels and the imperial city of Hue with filmmaker/professor/author Dr. Jean Pierre-Isbouts, share the Taj Mahal with author/historian Diana Preston who wrote a book about the treasure of India, or visit a local Thai market with guest chef, Azmin Ghaherman.

"Our guests seek distinctive experiences, wherever in the world they travel," says John Stoll, Crystal Cruises' director of land programs. "The expertise of Dr. Pierre-Isbouts, Chef Ghalerman and Ms. Preston add depth, personalization and exclusivity to the Crystal Adventure excursions."
