This tour was wonderful and this was a super fun activity!
Our guide was Julian, and we really liked him, he was very easy going, knowledgeable and a pleasure to be with. The length of the tour is just perfect too, just enough to enjoy the activity but still have time for another afternoon adventure.
And since you'll be in North Pole, go see the giant Santa and visit the nearby store with all things Christmas. There are some reindeer at the farm next door that you can watch through the fence. :)
