我想在火车上预订一间套房。

I would like to reserve a roomette on this train.

我想在火车上预订一间套房。

"Hey, Robin!" I grabbed her as she passed my roomette.

“嗨，萝宾，”当她走过房间时我叫住了她。

On this trip I had a roomette, which put me in the privileged sleeping-car category.

但是在这次旅行中我订了一个包厢，所以我就被归入卧铺乘客一类了。

I was blissfully comfortable and happy in the cocoon of my roomette, but far too wakeful to sleep.

我的小房间还算舒适，但是我太警醒睡不着，我不知道为什么黑夜不会降临到我头上。

Had I been sharing the roomette, she would also have made up a top bunk that folded out of the way during the day.

假如包厢里要住两个人，那么还要铺一个上铺，到了白天这个上铺就折叠起来。
