Tonder
I'd recommend Tondor (EKTD), just north of the border with Germany. It's useful for filing / closing flight plans etc. I've stopped in their club house a couple of times. Hotels in town, about 20 minutes walk away. They also let us hangar the aeroplanes during very windy weather.
Stauning (EKVJ) is also worth a visit, as there's an interesting museum on site.
Safe Flying,
Richard W.
