I am sure there are a couple of threads that discuss overnights, you may want to do a search. One is https://www.companyofmen.org/threads/overnights.142186/#post-1611319. I am sure there are others. For me I so not like to eat before I have sex so in general I would always have light appetizers and some kind of drink and then have hot and heavy sex. When that is done and we have taken a nice shower we go out to eat for dinner. There isn't much I really mandate except I make sure I leave time for him to answer a phone call or two. Then we probably would have sex the next morning and I always either make breakfast or ask if he wants to go to breakfast. He might not and generally that is not part of the overnight. For me, for an overnight, I do not leave "time" for him to be by himself as I would if it were a full day or two.
