China HSR
I can even ask the hotels to help? Wow thats great to know. Thanks =)
Yeah, they might impose an admin fee though. Nevertheless, if it's your first time, go through the hotel concierge to save the hassle.
There are 3 classes of seats for the G trains (Inter-city High speed) between Shanghai and Beijing.
Class of seat ---- Chinese name ---- Seating configuration (like an airplane)
Business Class - Shang wu wei - 3 in a row (2x2) - First cabin of a 16 cabin train only.
First Class - Yi deng wei - 4 in a row across (2x2)
Second Class - Er deng wei - 5 in a row (2x3)
Since it's a 5+ hour ride (depending on the
train schedule), I suggest to take the First Class seat since it's wider and you'll have more space to store your luggage in the overhead compartment.
Remember to tell the concierge you want a first class seat. If you don't, by default it's second class.
I like taking the high speed trains when I travel in China (leisure), it's convenient and it's an experience by itself, 300km/hour.

If you want to ride at a specific timing/train based on the schedule, I suggest to book at least 1 day in advance (another reason is cause the paper ticket needs to be delivered to the hotel).
