Are the outside activites open in the winter

Weather permitting, yes.

Pending weather

We went last weekend, and though it was in the twenties outside, the car track and mini golf were open. Staff were waiting at the back door to allow us to use the go karts. Actually, they let us run around three or four times in a row because no one else was in line. It was frigid though -- bring your gloves and coat!

Yes, weather permitting.
