One possible version：

Dear Nattawa,
    I’m going to enjoy a tour in Thailand during my winter holidays with my family. The good news is that I have booked the air tickets to Thailand successfully. But out of my expectation, when I visited the Thailand Train Ticket trying to book the train tickets, a notice caught my attention, which said that all the tickets had been fully booked from January 20 to February 28. Now I’m writing to you asking for help. I wonder whether you are kind enough to tell me how we can rent a vehicle in Thailand in order to ensure a self-driving travel. Surely, I’ll appreciate it very much if you can be our guide.

Looking forward to your early reply.

      Yours,

      Li Hua

亲爱的nattawa，
    在冬天，我与家人度假，我们要去享受泰国之旅。好消息是，我已经成功订好了到泰国的机票。但出乎我意料的是，我去泰国要坐火车，要订火车票，通知引起了我的注意，它说，所有的票从一月二十日到二月二十八日已经订满了。现在我给你写信求助。我想知道你是否能告诉我们可以租到泰国车辆，确保自驾车旅游。当然，如果你能做我们的导游，我们会非常感激。
    期待你的早日答复。
