BIL is turning 40 in December. One of my ideas is a day + overnight trip to Toronto. We're only 1.5 hours away on the expressway. I'm sure I can find a decent deal for one night in a hotel.

Anyway, any ideas for some fun adult activities in/around Toronto worthy of a 40th celebration? *Possibly* including a toddler for some portion of it?

P.S. We've all been to TO so nothing touristy please.

I'm only at the idea stage....
