It is beautiful.....but also not what I expected. You can see a lot of sculptures, both from Ice and from snow in this festival. It was good but I have seen better in Haerbin, China. There are also a bunch of performances and you can buy food from the many stalls that lined the festival areas. However, the prices for accommodations during this time would double (or even triple!). So, if you want to see this festival I suggest you book your stay months earlier. The same thing also applies to airplane tickets.
