Squash and family sports ideas

Good morning all,

A couple of questions I hope someone can help me with.

First, I would love to learn how to play squash. Does anyone know a class/coach/gym I can look into? Brussels is fine or Rhode St Genese/Waterloo/Lasne where a friend may join in, or nearabouts, but prefer a morning class.

And two, any suggestions for a sports activity and club a family can partake in together? Kids are between 8 and 12. Something like a weekend rowing/family hiking/I dunno - but age-appropriate. Golf is outside our budget!

Thanks for any suggestions on either question, and have a nice Monday.
