First let me make clear that we went in June, not during the annual February attraction.
The sculpting was really cool to watch! The ice sculptor (Neil) went out of his way to engage the kids (giving them ice shavings) and we had a nice, friendly conversation with him.
As for the museum?? Honestly, nothing special. A short video and then a 5 minute walk past various ice tools.
Obviously the time to visit is in February!
