What do you mean by the guest at the back of the hotel room?

Generally speaking, the standard for hotels to distinguish domestic and foreign guests is this-domestic guests: guests with mainland ID cards. F: Guests with certificates other than "Mainland Identity Card". Due to the different standards of some hotels, please refer to the drop-down box of "Proof required for staying in this room type" on the order page.

Reservation for domestic guests means that the document used for reservation is "Chinese mainland Identity Card".

Extended data:

Usually, hotels may have different prices for domestic guests, China guests and foreign guests, so this area will also be distinguished on the hotel reservation website.

PS: China guests refer to mainland tourists and foreigners with mainland work permits.

The appellation of domestic and foreign guests is mainly aimed at travel agencies with entry reception qualifications. Compared with domestic guests, the standard is low (reflected in the hotel's few stars, low meal standard and low price), while foreign guests require certain reception conditions (reflected in the hotel's arrangement of single rooms, meal elevation, attention to dining environment, car vacancy rate and high price).
