Oh dear Harry, you seem to have a big chip on your shoulder about Ostend. It can depend on where you go, just like any city or town. But, as already said, the Belgian coast is wonderful. As for the motorway, done it many times. Again it all depends what day and time of the year you use it. Whatever, certainly no worse than the M1 or the M6. As well as the moules frites, you haven't lived if you don't try the tomates crevettes!
