I know that the answer to the question "What happened to expand tourism in Nepal?" is in "With the opening of the tourist industry after the change in the political scenario of Nepal in 1950, the hotel industry drastically improved. Now Kathmandu boasts several luxury such as the Hyatt Regency, Dwarika's, theYak & Yeti, The Everest Hotel, Hotel Radisson, Hotel De L'Annapurna, The Malla Hotel, Shangri-La Hotel (which is not operated by the Shangri-La Hotel Group) and The Shanker Hotel. There are several four-star hotels such as Hotel Vaishali, Hotel Narayani, The Blue Star and Grand Hotel. The Garden Hotel, Hotel Ambassador, and Aloha Inn are among the three-star hotels in Kathmandu. Hotels like Hyatt Regency, De L'Annapurna and Hotel Yak & Yeti are among the five-star hotels providing casinos as well.". Can you tell me what it is?
