Could Skating Arena attendance be increasing by Disney's Frozen?

My nephew went to a little girl's birthday party at a skating rink yesterday and all the girl parties were Frozen related. Frozen was released in 2013, most little girl parties have been Frozen.

 

I didn't find an article about Frozen influencing increase but attendance is up:
