We did this last year and I've already signed us up this year. I'm super excited that Baby Ripples will be old enough to try to bowl this year.
If you have kids, check out Kids Bowl Free. It's a great program that lets kids bowl 2 games per day all summer for FREE. Just find a bowling alley near you that is participating and sign up. It's completely free! And if you want a pass for the adults, its only $24.95 for one pass that allows 4 adults to bowl all summer long! All you have to pay for when you go bowling is the shoes if you need them.
The days and hours are limited by the bowling alley. We are lucky to live 2 minutes away from a participating bowling alley and they have free bowling hours Tuesday - Friday until 8 pm. It's a nice, cheap family activity to do on a Friday Night to get the weekend started!
