还有没有空房间？英语怎么说？

语言是活的东西，无所谓对错，全看习惯。楼上几位说的基本正确，但在美国的实际生活中不这样用，一般就是: Do you have a room? You got a room? Can I (we) have a room? 在旅馆订房这样说就可以了。本人来美十年了，是美国永久居民，应该还可以，仅供参考。

Do you have a room available?

Is there any room available in your hotel?

Is there any empty room available?

Is there any vacancy available?
