In short , You will get all functionality of product.product object into 'hotel.services' object.

when you create record in hotel.services at that time its related record also created in product.product object.

product.product work as parent and  hotel.services work as child. so child will get all functionality of his parent.

you can access fields of product.product into hotel.services. Even in form/tree view of hotel.services, you can define Fields of product.product.

Its inheritance concept

    product.product -> hotel.services

same like:

     product.template -> product.product,

    account.analytic.account -> project.project.
