My wife and I have visited Bruges before and know that it's a beautiful place. Both the previous time and this time was on a cruise ship so time is limited. On this occasion we chose to do the praline-making experience rather than wander around town. Sadly we also didn't have the time to look at the museum properly as we're told that it's been significantly overhauled since our previous visit. We have no doubt that it remains worthwhile visiting.
So, the chocolate experience. It is what it is. It is fun, as expected. A group of maybe ten of us gather around in a kitchen which is disability-accessible. We had to wear disposable plastic aprons which, aside from the hygiene aspect, are essential as this can get messy. Again, it's fun.
The guide has enthusiasm and energy. You get a choice as to what sort of chocolate to use. The whole experience is quite short but we did get to bring our chocolates home.
If you have the time, which is certainly a factor, I recommend you doing this activity.
