Meal conditions are always indicated in the rate description — for example, you may see a note "Breakfast included". In most cases, this means that breakfast is included for all guests on the booking.
In rare cases, breakfast may not be included for all guests in a booking; then this will be further reflected in the rate description.
If the hotel has specified the type of breakfast provided, such as buffet or continental breakfast, you will also see this in the rate description.
