Where to Stay: Brussels, Bruges, or Ghent?

There's no one really good answer to this, all the cities have their advantages (and their fans / detractors) if you are just considering ease of access for a normal traveller. You can travel really easily between the cities by train if it is just a small group and so the answer doesn't matter much. However, I think the easiest would be to base in Brussels with such a large group. If you are travelling by train from Paris, it will be more straightforward to just travel directly to Brussels and stay there. The Eurostar hub is Brussels and there are no direct trains from Paris to Bruges (although you can get off at Lille Europe, walk to the Lille Flandres station with luggage and 25 people, and change to another train in Kortrijk and change again. No, that would not be for me.). This is not to say that Bruges and Ghent are not worthy, but I am thinking it seems less complicated to me to just go for Brussels. There might be a different answer if you were all travelling everywhere by bus (I don't know - what are your plans??). Obviously the bus driver would know also whether their bus fits into all those narrow medieval streets. In Bruges tour buses stop off near the Begijnhof (Beguinage) and drop people off there and pick them up again at the end of the day.
There will be others who say go for lovely Bruges or striking Ghent, but I am thinking mainly of logistics. I would rather take a group of people without luggage on the Belgian trains with me. You might get some varied opinions on this!!

I teach high school and also took some young folks to London last year - admittedly not this large of a group. I really like Bruges. It is an easy walkable town and It quite safe. Its is also a very Instagram type of medieval town to wake up in, early morning gets you the best photographs and I know that age group like their photos. There are boat trips, horse drawn carriages, lots of chocolate, French fries, Belgium waffles, lunch cafe's. We even did a bike ride to Dam along the canal - had lunch and rode back. Very cheap to do. A day trip to Ghent would be possible as the train station is easy to walk to. Other's may suggest Brussels because of the logistics but Bruges is just delightful.

I'd go with choice 2; stay in Bruges and 1 day in Ghent.

Maybe it's just me and group travel...but after being all together in France for the main part of the trip allowing folks to go their own ways a little would be easier in Brussels. Some to Bruges, some to Brussels museums if they need one or two more... or just scarfing waffles or mussels. Also you will want to be in Brussels the night before your flight anyway.

I vote for Bruges. It's charming, picturesque, a small town, and comfortable. Folks could go off on their own, following their interests. There's the tower, (remember the movie?) the chocolate (I threw out most of my clothes to make room for maximum chocolate), a canal cruise, the haunted evening tour, chocolate tours, and the beer/ breweries. There is actually a beer pipeline under the town.

Ghent is a great day trip, and the Monuments Men movie Alterpiece panels are there, and the related VR Tour is fantastic.
Kudos for organizing this. Have a wonderful time!

Ghent is a university town. If you are going with a group of 17 to 23 year olds, I would bet they would prefer Ghent to Bruges or Brussels. Although any of the 3 towns are worth your time.

mpaulynsettle, I'm a high school teacher as well!

Thanks, everyone, all of these are excellent suggestions. FWIW, we'll be taking the train from Paris to Brussels. Since the young people are not younger teens, they are capable of choosing their own adventure. I was planning on making this less structured than the rest of the trip anyway, which will be done through a tour company. I suppose we could also give them options on what they want to do and split up that way. Given what I've heard about Bruges, that does sound like it should be on the agenda, but maybe some people might want to go to Ghent for one of the days too, instead of another full day in Brussels.

Bruges is the most marketable and for cocktail-parties-back-home conversation. A more sophisticated choice for a group of self-starters might be sleeping in Antwerp. But if your daily schedule will be the choice of 95% of the group, Bruges.

If your schedule coincides with Feesten in Ghent, that's where you'll want to be.

Thanks, you've both given me some additional considerations!

I loved Ghent. I stayed there for three nights and did a day trip to Bruges, which was the perfect amount of time for both. I enjoyed Bruges, but the crowds got to me a bit and I was happy to get back to Ghent for the evening.

Ghent was wonderful and is perfect for people who love history, charm, and local culture without the crowds of Bruges or Brussels. There are picturesque canals, bridges, and cobbled streets and lots of historic and beautiful sites. I agree that if you are coming with college age kids, they would probably enjoy Ghent more. Ghent is a university town, so it’s got a real youthful energy about it. I definitely preferred the "lived in" atmosphere of Ghent to the crowds of Bruges.
