Can men and women live in the standard double room of Shanghai Hotel?

Yes! Some hotels will require all four of you to register ID cards. For example, Greentree Inn and Jinjiang Inn are strict, and some hotels don't care who you live in.

Last time, I shared a standard room with four colleagues. We didn't book two rooms because of limited financial resources. We just registered our ID cards. No one will care if you are a man or a woman.

In fact, you can find a quadruple room in Youth Travel Service, and the price is not much more expensive than the standard room. Some hotels have bunk beds for four people. For example, Wan Li Road Youth Hostel, International Youth Hostel and so on.
