I am not aware of any airfield in Belgium or the Grand Duchy with a hotel on the premises. Have some memory of EBSH Saint hubert, though, in this respect.
There is a hotel open at Saint Hubert. Stayed in it last month.
Here is my trip report.
Very nice trip report. You seem to have visited many airfiels in a short time!
It clearly shows how nice VFR flying can be... Very inspiring :-)
What a wonderful photo report. Some beautiful airports there.
