Can a three-person standard room in the hotel accommodate many people?

Hotels generally don't make rounds,

Even if you make rounds, you can answer on the grounds of temporary visit and late departure.

After checking in, people who want to stay should not go in together.

It usually takes several time periods to enter, so as not to attract the attention of hotel service personnel.

The last few people who go in had better not bring their luggage to avoid attracting attention. Baggage can be brought in first by the person in front.

Keep a low profile when you go in so as not to attract unnecessary attention.

Go in the morning and pay attention to walking in batches.
