The key is that you have your own space, can work to your own rhythms. So no other couples or friends on top of you, demanding your attention or trying to dictate what you do. They must respect different choices and boundaries.
Eating together in the evening whilst doing different activities during day can work. But you must also respect if they decide not to eat with you some evenings. Some with activities, not one should be forced to continue with something if their heart is not in it. So if it is a mountain walk and a friend or couple decide to turn round half way up, don't make a big thing of it.
Some like to be super organised, others like to take a day to day approach. Again both need to be respected.
