Almost 10 years ago, Priya Sachdev, a graduate of the London School of Economics, model, and actress, and Vikram Chatwal, the son of a New York hotelier, hosted a $20 million wedding that spanned 10 days. 

This extravagant wedding included 600 guests from 36 countries, who were flown in by private jets provided by the groom and bride. Beyond the ceremony and reception, Vikram Chatwal expressed his desire to showcase his home country to his international friends. 

Over the course of the 10 days, they visited three Indian cities: Bombay, Delhi, and Udaipur.
