We went as a whole family - so four households - and shared a big lodge.
My mum doesn't sleep well so stayed in a nearby hotel as she didn't want to disturb anyone else when she pottered around in the night. She joined us during the day and for meals.
We took turns to shop/cook etc and all pitched in with the cleaning. Childcare was arranged so everyone had one night 'off'.
As long as it's clear that everyone chips in it's great, and sharing the chores means everyone has some down time too.
It worked much better for me than a self-catering holiday with just my own family as I would then be doing the jobs I do at home just in a different place!
Saving water, should we be more pro-active?
Locked room for breakables when grandkids stay?
"Old fashioned" expressions that young people have never heard.
