Do you mean, you need to rent accommodations + services, however, services should be included by default? If so, in Hotel Booking there is no possibility to make a service included by default, a guest should select it if needed at the Checkout page. Only taxes/fees can be added automatically to a booking (they can be created in the Bookings tab > Taxes & Fees). However, you may still add the needed services to the needed accommodation types but include their price to the acc. type rate and specify this information.
