We went and had a wonderful time. DO take hats and gloves like another poster mentioned. My older kids (7&8) would have stayed on the slides for a week if they could have. We were probably in there for close to an hour with all the kids sliding like crazy. But then they were so cold when they finished that they sort of ran through the last part. Let everyone slide on each slide, go to the end and then go back to the slides. It is awesome and my kiddos really enjoyed that as one of the best parts of our trip. BUT we live in FL so they have never seen snow and ice. For our northern friends, it might not be a novelty to you!!
Enjoy!
