Euro Space Center (Space Camp) Experience?

I'v been looking at the Eurospace center in Belgium for a present for my son's 10th birthday. We live in Paris, so I dont think i'd be comfortable with sending him for a week, but they do weekend programs during the holidays. I can't seem to find any unbiased reviews, though. There is plenty online put out by the center themselves. I've also found school reviews (from teachers who took their classes on field trips there). I've also found reviews from people who have visited their museum (or the center, but just for the day...) I really am concerned with the sleeping facilities, the safety, the councilors, etc- so I'd like an outsiders opinion. Has anyone gone or known anyone who has gone before? Also, has anyone ever heard of the town before- its called "Transinne" ? One option I thought was to take him during the day, spend the day sightseeing or whatever while he's in the class, then spend the night in a hotel- but I don't know if there'd be much for me to do during the day there... Any info would be greatly appreciated!! Thanks!
