My in-laws live in a medium-sized U.K. city that is a popular tourist destination. When we visit them (DH, self, 3 DC) they stay in the house the entire visit.
An example day: breakfast in the conservatory, then sitting room, then lunch in the conservatory, back to the sitting room, dinner in the dining room, followed by TV in the sitting room before bed. Lots of tea. Never leaving the house for the length of our 3 or 4 day visit. No solo time, lots of polite chat.
My in-laws are in their early 70s, middle class/no money issues, mobile (actively pursue hobbies) and don't have health issues. Is this typical of British people, do you think? I'm a long-time UK resident but not British. A typical visit with my family would be broken up with lots of trips out and some alone time (e.g. walk in a local park, dine out for either lunch or dinner, maybe go to the cinema).
This way of hosting makes me quite claustrophobic, although I do get on with my in-laws. I usually assign myself errands when we visit ("I'll go get milk," "I see there's a new bakery that opened, I'll take the bus there and pick up something") which I think they might find strange but I simply can't stay inside all day :)
