Beijing's top hotels are fielding scores of calls from foreigners and Chinese people eager to book rooms during the 2008 Olympic Games in the Chinese capital. The luxurious and recently-renovated Beijing Hotel said it had received nearly 100 telephone inquiries from people wanting to book rooms during the Games since Beijing won its bid to host the event. 'Out of these people, foreigners make up 30 to 40 per cent, including people calling from the United States and Europe', a hotel sales manager surnamed Song said. Minutes before the decision by the International Olympic Committee (IOC) was announced in Moscow, the hotel had already received 50 to 60 such phone calls from would be game-goers gambling on the result. Domestic callers have mainly come from the southern provinces of Guangdong and Fujian.
