Here are my picks for the best happenings at theme parks and attractions for 2012.
•Best new costumes: Storybook Circus, Magic Kingdom. Step right up and see the red, ringmaster-inspired costumes — complete with tails — that fit the color scheme and theme of the New Fantasyland subsection.
•Best (and biggest) costume change: Diana Ross, Mardi Gras concert, Universal Studios. The legendary singer found ways to keep warm last winter, including a gown that made a grand entrance for her finale. That dress may — or may not — have had its own airplane seat, rumor has it.
