I drove to France and Belgium last year.
The idea was to drive over, spend a few nights in Bologne and check out the sites, food and drink, find a cheap hypermarket and come home.
The plan changed slightly when we arrived at the "hotel" in Bologne and it was a dive. I've stayed in worse but the other lad I was with didn't fancy cuddling up to mysterious things in the bed so we whipped out the ipad with the WIFI and searched for somewere else.. We ended up staying in Dunkirk. Quite a nice place, the obvious history along with it and had a bumble down the sea front for food and beers in the evening. Inbtween the s**t hotel and Bologne we stopped off at La Coupole which was a V2 Rocket launch centre run by the Jerries. Now a museum and was pretty decent.
Day after we arrived we drove from Dunkirk to Bruges for the day. About a 40 minute trip, not very scenic, just like the M1 but smoother and on the wrong side. Parking was like a fiver for all day and we looked at all the markets, went up the belfry and did the boat tour and brewery tour. Not a cheap place but awesome visit. Perhps going back this year and actually stopping there so we can drink a bit more lol.
