Will a hotel booking API tell me if breakfast is included in the room price?

Yes, in most cases a hotel booking API will tell you whether breakfast is included in the price of a room. Hotels send the meal arrangement along with each room they offer, and it usually arrives as a short description such as room only, breakfast included, half board or full board. Your portal can show that wording next to the room, so your customer can see what they are paying for before they book.

How clearly this appears depends on the supplier the room comes from. Some suppliers send a tidy code that your portal can turn into the same simple line of text every time. Others put the detail inside the free text of the room name or the rate description, and then the wording can change from one hotel to the next. Because of that, your customer may sometimes read the hotel's own phrasing rather than a neat standard phrase, and a few room types may not mention meals at all.

It is also worth knowing that breakfast being included is not the same as everything being paid for in advance. In many places a city tax or a service charge is still collected at the property, and that is separate from the meal arrangement. When a room says breakfast is included, that refers to the meal only, not to every possible cost at the hotel.

Before you go live, run a few searches in the cities you sell most often and check how the meal information reads on your own pages, and tell us if any of the wording looks likely to confuse your customers.
