Belgium's Wanderlust runs private, all-inclusive day tours for small groups, never more than eight guests, with door-to-door pickup from the hotel.
Each day is built around the guest: castles and Trappist breweries around Dinant, the memorials of Flanders Fields, or a single curated day across Liège, Aachen and Maastricht.
One guide, one car, the whole day handled.
