It is a huge indoor area with snow where people can ski and snowboard and have fun with toboggans. It is just around 15 minutes drive from where we live and at first we didn't tell Bianca what we planned. She was so curious and kept insisting we tell her what the "surprise" would be. She did figure it out when we had to turn by the sign that said "Snow Planet" with a right arrow which of course she read and then asked "are we going to Snow Planet?" She got so excited that she could hardly wait to get there.
We took most of the warm clothes she would need along with us, but rented the snow boots and snow pants (which of course we don't have because we don't get snow in winter here in Auckland). And in hindsight we should have arrived maybe 20 minutes earlier than planned because that's how long it took Terence and Bianca to get dressed into their snow gear.
