A first grader asked Mary the typical question: "Where's your crown?" Mary answered: "It's at home." And added in a whisper: "It's not a real crown as such." - And later elaborated that she doesn't wear tiaras often.
So that means the town of Skagen. No surprise, they've been there often. But AFAIK there have been no reports of sightings.
A very likely place is Birkelse Estate, the home of the Skeel family. Also a place M&F have been many times and it's pretty undisturbed.
And the of course they may have spend time at Trend lodge. Not the best place to spend a summer if mosquitoes are fond of you though!
Here are a couple of pics of Birkelse.

Birkelse is an archetypical Danish 17-1800s estate, in the sense that while stables and barns were hidden out of sight at say English manors, in Denmark you pass the stables, barns and so on, before you even get to the manor house.
This was a matter of pride, you showed off how well kept and successful your estate was, for visitors to admire and a topic for discussion later.
There were of course a number of nobles who didn't care about their estates and who were rarely there - they were looked down upon by their peers.
This goes way back before medieval times. A noble was supposed to know about his estate, know in broad terms at the very least how it was run. He was supposed to have a very good knowledge about agriculture and livestock.
So you could expect to meet him all over his estate - and of course take off your hat, bow and address him in third person. (Third person address was BTW a normal polite way of addressing people.) He was also expected to know his tenants by name - not the children and secondary relatives, but the husband and wife of a tenant farm would certainly be known by the noble.
After all the noble would give his permission for you to marry and probably have a hand in arranging a marriage on a tenant farm.
That was a mix of social security and practicality. Say a woman on a tenant farm became widow at 40. Instead of kicking her out, typically a suitable young man would be found - a solid, competent reliable man with a good reputation known by people in area, the local priest, the steward and perhaps even the noble himself. That young man might be in his mid twenties and the second or third son with few other prospects of getting a farm.
That meant a big step up the social ladder! It also meant he would get an experienced wife - who would be cared for. She probably had a few children, so that was extra free help on the farm. They were perhaps unlikely to have children, but he could have some with a farm girl and perhaps even marry her later on. People had a very practical view on illegitimate children.
So it was a marriage of convenience and a win win in most cases in fact.
He would be unlikely to abuse (too much) his wife, because she had relatives all over the area, some might very well be married into his family. And if need be he could lose his tenant farm, which meant destitution - and likely shunned by his family. After all he blew an opportunity many dreamed about.
After all you managed your estate for your children and grandchildren.

- Oh yes, there were also nice pics of neat looking children and the most presentable teachers in the background.
