Harbin 2013

Hello,I''m looking forward in visiting the Harbin snow festival in Jan 2013, and am very interested in taking part in snow activities. We are 3 adults traveling and want to confirm wither most of the activities available are for children only. And if there are activities provided to adults, can we book a customized snowmobile tour for a couple of hours in Yabuli Ski Resort.Kindly advise, thank you.
