I always make sure I get up with guests and try to provide a more "special" breakfast - croissants, rolls, yoghurts, fruit, cheese and cold meats, cereal set out on the table for when they are ready. I usually say what time breakfast will be the night before and check it's OK with everyone. It's always worked fine, and it's nice to all sit down and chat over breakfast.
Most of my family and friends are the same, breakfast is a big deal, everyone eats it together, if you've had guests you make a bit of an effort - cooked breakfast, bacon sandwiches, pancakes, that sort of thing.
But DH's family, when we stay with them just have breakfast as and when, don't all sit down together, and we have to get our own. I don't like it because it isn't what I am used to - I hate rooting in cupboards in someone else's house.
I think some people just have different expectations of breakfast! To me it's a meal with the same social rules as lunch or dinner, but others see it as a more solitary, grab when you're ready sort of thing.
