First ,I got some information on the Internet. 应该是got some information from the internet 或 searched some information on the internet 注意介词的搭配
So we knew what the weather would be like and we decided when to go .这不是一个完整的句子,如果要用So的话前面应该有句子阐释原因,所以建议你把前两个句子连成一个完整的句子,比如：First ,we got some information from the Internet , so we knew what the weather would be like and decided when to go. 统一一下主语,并且在后面不需要赘述一遍we了 直接用并列格式更好一些.
In addition ,I booked two train tickets and a hotel room .
in addition用在这里感觉怪怪的.但语法上应该问题不大.
About some hours latter ,I went to the store which sells train tickets and got my grandparents` tickets. 这句话给我理解上造成了一点混淆,不是之前已经说过了book tickets为什么现在又要got tickets?如果只是取票的话还是picked up tickets好一些.
After I went back home ,I helped my grandparents to prepare their clothes ,also ,i bought them a map of Beidaihe . 首先help ... prepare 不需要加to 其次这个句子应该被拆分为两句：After I went back home ,I helped my grandparents to prepare their clothes. Also ,I bought them a map of Beidaihe. 在同一个句子里赘述两个不不相干的事情是很奇怪的.另外还有就是句子的顺序需要调整一下,既然都已经went back home了还怎么bought maps.
At last ,I drove my grandparents to the train station. 这句还好
After seeing them seated on the train ,I said "Bye bye "to them ,and I didn't leave the station until the train started moving . 首先seated不是动词而是形容词 不可以这样用 其次前面这个after非常怪.因为这些动作是连续发生的,所以个人认为更好的表达是：
I saw them get seated on the train, said "Bye bye" to them and stayed in the station until the train started to move.
个人改东西比较picky一点.但因为也不是native speaker所以也可能出错.
互相交流.请多指教.
