Is the reception room a free room?

You can't. The reception room of the hotel is for the public relations needs of the hotel, but it needs to be paid internally (such as mini-bar or laundry fee, etc.). According to the agreement of the reception, only for some people, the free room is free for everyone, so the reception room is not a free room. The reception room generally refers to the private reception hotel of the unit, which is specially set up for the internal or business departments of the unit and is not open to the public. There are different rooms to entertain different levels of customers.
