1）只要护照就可以了，有些人比较烦的话会要求看你的签证或者学生证
我的建议是带齐点比较好

2）价格低于50S$以下的一般条件都不怎么好,个人推荐PASIR PANJANG INN，60块钱一晚，虽然价钱只差10多块钱，但是房间条件有很大差别。我的经验是很难有小的SINGLE BED ROOM那种，一般的SINGLE BED都是一个双人床，价钱和双人间的标准间一样。

3）关于旅行团，恕在下没有这方面经验。不过要是长期居住，有些宾馆象PASIR PANJANG INN可以减到50S$/night. 另外，CHINA TOWN的大华酒店条件也不错，看你选择了。

i have different opinion with u.

i c so many couples to live in one room, and not so strict as u have said.

the lowest one may be 10S$/night, but the condition is very poor.

commonly, the price for the hotel is 60S$/night.

however, if the guy has enough money, he can rent the room of some hotel which is more than 100 or 200S$ per night.

i promise what i have said is TRUE.

pls believe me, thx
