It seems they have made a big improvement from the previous year. The ice rink is located beside the serendipity restaurant and it's real ice, not that fake plastic stuff the other casinos use. The price was 2 for $25 for locals at the time I went, and that was good for up to 6 hours. There's also professional skaters there that help you out if you're a beginner. I think it's definitely worth checking out. Even if you don't know how to ice skate.
