It's in the middle of nowhere, so nothing else for the kids to do i'm afraid. There is food outlet on site, as well as a gift shop.
Take a shitload of money, as guess what....it's expensive. The programme is a tenner, so you can imagine what the rest of it is like.
But, your kids will absolutely love it, so well worth it to see the look on their faces. You're going to be a very popular dad for at least 25mins after you come out!
