By train: Beijing to Hangzhou
Browsed through a few informative sites. Still have a few questions about travel by train from Beijing to Hangzhou. I've done Shanghai to Hangzhou, but not from Beijing.
1. Does G33 (and/or G1) go from Beijing to Hangzhou via Shanghai (ie stop in HQ; or change train in HQ)?
2. Possible to book ticket online with US credit card? If so, web site please?
3. Prefer fastest trains, are they booked up early? How far in advance should I buy ticket if I have to do it in person at South Station?
TIA.
