Hi,
We stay in Beijing on April 24th. Can we order the following tickets online now and to have them all deliver to our hotel upon arrival?
1. Turpan to Dunhuang (overnight train April 29)
2. Dunhuang to Jiayuguan (evening train May 1)
3. Jiayuguan to Lanzhou (overnight train May 2)
4. Pingyao to Datong (afternoon train May 5)
5. Datong to Beijing (May 8)

Could you give us any suggestions if you have problems to book train tickets online on May 1 and May 2?
