NOTE: The last day you can visit the Maelstrom attraction is October 5, 2014. Although the ride will be closed after that date, the Norway pavilion will remain open during construction.
Elsa, Anna and some other characters from Frozen will also make an appearance during Mickey's Very Merry Christmas Party (an event which requires a separate admission ticket).
In addition to their regular character appearances, you can see Queen Elsa use her powers to transform the castle into an ice palace each night Nov 5. Check daily show schedule for times.
