My humble opinion is that Houx Annexe, although without hookups, is a good all round well positioned site within an easy walk of the village area and Tetre Rouge.
There's generally a fair amont of space, and plently of friendly faces.
We plan (ACO permitting) to be on there again next year, 20 of us in assorted cobras and classic American iron (1932 Ford Pickup, Cadillac, Lincoln etc.)
All the best
