Just came back from my honeymoon in which I spend 2 nights in Brugge and wished I spent more tiem there, it was definitely the highlight of my trip.
Although there were lots of other tourists around, it wasn't overwhelming. I enjoyed the fact that there were lots of locals there too, it wasn't just a tourist destination. Food was great, the people were very friendly and helpful when I tried to use the 3 words of Flemish I learned there :-) and most of all, I never felt like I was overcharged for anything (like in a lot of other tourist centres) even the canal tour was a reasonable 6 euros! I can't wait to return. I would also recommend renting a bike there if you can. It was a great way to see the more resedential (but still gorgeous) parts of the city.
