We got a chance to go again this year. It was very cold but still a lot fun. Last year, it was snowing when we went so we were soaked; this year, it was just cold.
I was also able to take the kids again to the North Conway Grand Hotel's outdoor hot tub and heated pool. Sure, it was -23 degrees outside (that's not a typo, our hair was freezing instantly after it got wet), but it was fun. Here's a short video.
