No. The dining plan covers the surcharge. The surcharge is usually an extra $4-6 dollars around the Holidays. I know, June is not officially a Holiday, but they roll Father's Day, and July 4th together and call it "Holiday Pricing". They do the same thing around Easter.
Spring/Summer Holiday surcharge dates are April 5-18, 2009 and May 24 - July 11, 2009 at:
Akershus Royal Banquet Hall (Princess Storybook Meals)
