City Convenience Hotel (Shantou Railway Station Branch), can the double room accommodate 3 people?

Of course, the price you pay is for a room. As long as there are not too many people staying in your room, the hotel will not interfere.

I once stayed in a hotel with a family of four. room.

However, the hotel only has 2 beds, so you need someone to occupy one bed;

Of course, you can apply for an extra bed, but you will need to pay extra.
