You do. It appears you don't understand franchising. Your contract is with the property, not Marriott. Marriott can enforce Bonvoy program requirements (welcome gifts, for example) but the broad hospitality deliverables are the responsibility of the property. If you have an issue get it resolved before departing the property.
