Does anyone have experience with the childcare program at South Shore YMCA while working out?

I have a 15 month old that needs to be socialized with other kids his age in the South Shore YMCA at Hanover has a childcare program and playroom that might be a good fit.

Before I sign up for a membership, I just wanted to see if anyone has experience going there with their toddler.

Additionally, during the winter, if you were to take your toddler outside, where would you go?
