Kids have so much pent-up energy that you can’t keep them inside your home all of the time. But when the weather isn’t cooperating, you need to find new walls to climb. These eight destinations welcome drop-in families anytime. Just bring your socks (they’re required!) and spend an hour or a full day at these fun picks. Call or check websites for hours, which vary.
