If I had to take the dogs I would kennel them while at my parents' house. Regardless of how well behaved and wonderful your dogs are, it is their house and therefore, IMO, their call.
My mom doesn't allow dogs in her home – never has, never will. I spent ten days there at Thanksgiving and the dogs had to stay in the garage all day {7 AM - 11 PM} in an ex-pen, next to an old woodstove. At night she allowed them indoors only in their crates.
We took them on very long walks {she lives on 30 hilly acres with deer, badgers, cougars, etc. around so there were lots of smells to keep them fascinated}.
Was it ideal? No. But they survived and my mom's home rules were respected.
My niece and nephew, both of whom have dogs, stay at area hotels and bring their dogs to the house when they visit, but the dogs never go indoors, other than the garage.
I don't think any of us would even think to question it.
