I have plenty of spare rooms so it's never been an issue for me. When my daughter bought her house she set apart the best (i.e. en suite ) bedroom for when I visit, she also bought a bed with a very firm mattress especially for me. It's not even very often that I stay over, but when I do I am always appreciative of her care for my well-being.
I'm sure your in-laws will be equally glad of a good night's sleep when they're with you.
