This has nothing to do with the particular hotel but with general questions. May I suggest that we concentrate here on specific questions about the Hilton Dublin Kilmainham?
PS:
Spouse stays free
Spouse stays free in the member's room on qualifying stays. This benefit excludes stays at Hampton Inn properties. This benefit does not apply at any hotel when the rate includes additional components (e.g., meals, activities, parking, etc.) that are quoted as a per person or per room charge.
As I said, most likely you will get the breakfast.
