Can a double room accommodate four people?

Legal analysis: This is possible. It is very common for four people to stay in a standard double room, but they must have ID cards, one for each person.

Legal basis: "Measures for the Administration of Public Security in the Hotel Industry" Article 6 Hotels must register for accommodation of tourists. When registering, the passenger's identity document shall be checked and the passenger's identity document shall be truthfully registered according to the prescribed items.

When receiving overseas tourists for accommodation, they must also submit an accommodation registration form to the local public security agency within 24 hours.
