Dont worry, its really relaxed there. I landed at Oostende, cleared customs(they scibbled something on a scap of pape in pencil!) had a nice meal overlooking the long unway. Then flew VFR to Theux,10 miles north of Spa, with a squawk all the way and great ATC all the way. Enjoy the flight and you will see the Belgians are very accomodating of GA traffic.
I would recomend a night stop in Oostende, the food is good, sea food especially, and the beer is well, Belgian
The menu for beer is more comprehensive than the food!
