We had expected to stay for a half hour. Three hours later we left. I mention this rather mundane detail because the owners of pensions in Brugge are known for their insistence on prompt check-outs. Being five minutes late truly means paying for an extra day. Because rooms are in such demand in Brugge, it is best to book ahead to be assured of getting a place to stay.
Pensions vary widely in atmosphere and quality.
If you are not an intrepid traveler, it may be better to consider the pricier but more comfortable hotels. Driving into Gent doesn't fill the visitor with immediate enthusiasm and anticipation. Unlike its pristine sister, Gent is more industrialized. It also has a life that doesn't depend on tourism, as visitors on limited itineraries will almost always choose Brugge over Gent. Nevertheless, I found Gent to be a far more interesting city than Brugge in many respects.
