We are planning our August trip, and weighing the pros and cons of going to Bruges for one night. I think it's cramming too much into our trip, personally. My son is heavily pushing Bruges. The truth? I think he just wants to stock up on liege waffles at the Carrefour. He brought home five sacks of waffles (50 or 60 waffles!) from our trip to Belgium.
I would love to go to Bruges - someday. It's just a lot of travel time and expense. I'd rather spend one more night in Normandy and see Bruges some other time.
