How many kilos of baggage are we allowed to take with us?

Hi, you can take along at most 20kg baggage for the journey.

Do you also know how we get the tickets if we book them now? Are they e-tickets or will they be delivered to the hotel a few days in advance?

Hi, I used the webisite below a lot for ticket booking. They delivered the tickets to my hotel in advance. It is very convenient. You can also try it.

May help!

Hi,

That is convenient. But how does that work? We arrive in Beijing at the end of March. I book the tickets now and they deliver the tickets to the hotel rightaway or in March?

Hi, generally, the train tickets can be booked ten days prior to departure. Thus you may not get the ticket right now. But at the end of March, once you book the train ticket, they will try to deliver it to your hotel. Don't worry! By the way, here is their email address: travelchinaguide.com|booking
You can also ask them more details about train ticket booking. Good luck!

thank you so much! I will get in touch with them!
