In some cases, additional items can be reserved together with the hotel stay such as breakfasts, massages, ski passes etc. In the OTA vocabulary, they are defined as services. Whatever the choosen method for sending reservations to the Hotel-Spider severs (push or pull), the services are defined using the same format in the XML message.

Format

Each service is decribed in one Service node under the Services node which is part of one HotelReservation. In order to link Services to RoomStays, an attribute "ServiceRPH" is added to each service and must be a unique positive integer. Then a ServiceRPHs/ServiceRPH node is added to the RoomRate node if one or several service(s) is to be attached with the corresponding room stay.

Here is an overview of the added nodes:
