China
An English-language website where you can buy tickets for almost every event in town - theatre, ballet, Chinese acrobats, Peking opera and more. They bring the tickets to you, and you pay on delivery. Good for those who don't speak Chinese.
Train tickets are sold from more than one ticket office, and hotels and hostels seem to have different sources.
So, if the tour/ticket desk where you're staying can't book you a ticket for the day or time you want to travel it's definitely worth asking at another hotel - they may find you the ticket you want from someone else.
