Do I need to refrigerate egg nog cookies/icing?

s-a-r-a-h

I'm making these cookies for a lunch potluck tomorrow at work and am not sure if I need to refrigerate the finished cookies since both the cookies and icing have egg nog in them. What do y'all think?

Late to the party.. but Id say yes untill maybe 30 min before the party. That recipe looks amazing.. might have to borrow it!
