For Alaska they do Frozen night--the last couple of years they had a Frozen deck party, Frozen menu in the MDR's. Last year the Frozen night was the Skagway day--they did the deck party as a Sail away party at 7:30PM--so that was cool! Leading up to it were 3 days of 'Anna's Chocolate Chase'--3 questions/day in the navigator (basically a scavenger hunt--write down what picture you see at that location)--if you leave the completed form on your bed after the 3rd day, you got chocolate!
