I was thinking about a situation where I have some super cooled steam which suddenly freezes to water.What are the entropy changes(positive or negative) for the system and the universe?

My thoughts:On transition from steam to liquid water the molecules gets more packed together which reduces their giggling around and hence, the entropy of the system would decrease. Since it is assumed to be a spontaneous process the entropy of the universe should increase.Is my thinking correct?
