樟宜机场的转机酒店一定要转机的客人才能入住

我是半夜抵达的，不知道没有下一程的机票是否可以去转机大厅，酒店方面给我的邮件答复原文如下：


"Please be informed that our Ambassador Transit Hotels are located within the departure transit lounge of Terminal 1,2 and 3 therefore in order for you to stay in our hotel you must have an arrival and or departure flight information.”



"and or"...到底是and呢，还是or呢。。。有没有实际经历过的游四海旅游儿传授下？
