Hi, We are going to Harbin on Jan 2 and have only 1 full day to see the sites. I understand there are 3 main sites for the festival. I was wondering if what I'd see in Sun Island would be the same as what I'd see in Snow World? I will be definitely going to Zhaolin Park as it is close to my hotel but was thinking if i should do both Sun Island and Snow World considering the time we have...or can I swing both?
