I think that one perhaps useful tactic is to never talk about what you are moving away from--don't even allude to it. Never say anything that could sound like, "We don't want to be around family." so, no mention of "no drama" or "taking a break."
No negatives.
Instead decide/define what it is you are moving **toward**--the positive. You want a romantic day for the two of you. You want to create a ritual that's just for your little family, as a marriage-enriching thing. You want to try out that new restaurant.
I very much agree. It works (better) for a couple reasons that I can think of.
1) Less hurt feelings. If someone says they don't want to spend time with me because it's too noisy and my kids set their cat on fire, my feelings will be hurt. If they say they are looking forward to peaceful time with a roaring fire, glass of port and a view of the ocean, I don't feel personally slighted.
2) Less to argue with. If you have offered reasons you don't want to visit, I could promise to duct tape my kids to the wall and hide all the lighters if you will come over. If you give reasons why you want to be elsewhere, I can't really say that ocean views make you seasick and port is for weirdos.
Of course, those truly dedicated to finding offense will do, but most people will want you to be happy.
