My brothers all like to camp, but I'm notorious as the "posh" one who prefers hotels.
We used to get together once a year for a camping/fishing/bullshi**ing holiday, and it took them two nights to figure out that I was leaving the campsite after everyone had turned in and going to a nearby motel for the night, returning before anyone woke up. They never let me live that down.
Hotel breakfasts...in the US, generally no. Those self-serve things are horrible, and not just the food, but the state of the people visiting them. Some folks think that just because the breakfast is in the hotel, they can roll down there in their jammies, with uncombed hair, unwashed face, and sleep crud still in their eyes and have breakfast. In public.
Higher-end hotels, the breakfast might be better, but it's usually not included, and it's pricey. We always find a nearby place for a proper breakfast. Breakfast is my favorite meal, so I like it to be treated right!
In Europe/UK, included breakfasts are much better, we've found, so we always plan on those. However, I like a little variety, so I'll usually suggest changing it up occasionally.
Some of my best vacation memories are centered around breakfast. The last time we stayed in London, we rented an efficiency apartment, and the breakfast they offered (for a fee) was from the restaurant next door, so we just ate there ourselves. We were delighted to find, on this little two-block section of street, three excellent places for breakfast, so we were happy with that.
