It's the self-appointed Earl Beatty cruise director speaking... !
Last year I booked the Danforth Bowl on the Friday of the March Break, and it was so much fun for the families who came that I'm doing it again. We the place to ourselves for 2 hours (6 lanes), and it worked out to be about $20 per family (note: the exact amount depends on how many families sign up, and the number of kids per family). I recall that each child received a drink and chips as part of this cost, and the adults happily ordered from the wine/beer selection, and paid separately for this.
If you are interested, please reply to email@example.com asap (we had a full house sign up pretty quickly last year). Because I have to pay the Danforth Bowl for our time there, and there are so many kids involved, the sooner I know who is coming the better. Ask your friends at the school too if you like, because it's great for us to support our local bowling alley! If we get more kids wanting to come than can be accommodated, those who don't get on my list can always be organized into a second group from the school.
