Hi Keisy,
Just a few ideas for your stay in Bruges.
There are 2 interesting museums there. 1 is the "Chocolate" museum, for all chocoholics and also there's the "Fries" museum dedicated to Belgian Fries
The group that would stop in Antwerp could eventually go to the "Quetzal" chocolate bar (drinks and desserts with chocolate) and next door to "Nine" one of the best lounge and cocktail bars in Antwerp, but I think it's closed on tuesdays.
Where is that group staying in Antwerp?
Since I just live south maybe I could give them some ideas.
I'm still checking if I can have a day off.
