I think Star Wars party nights to celebrate the new movies would be an awesome fit at Epcot.. especially considering using a projection on the ball to make it look like a deathstar in the same way they did the mike wikowski thing. I enjoyed the magic kingdom pirate parties and would definitely do a star wars party night or two at Epcot.
It seems pretty simple too.. 7pm to midnight party.. just throw the death star projection on spaceship earth, pump in various star wars themes over the park, some fog machines, a dance floor or two from the new years eve event to dance with characters, add a crazy star wars parade around world showcase, put on a show at the fountain stage, add in star wars characters for meet and greets, star wars themed fireworks, oh and with all the dining options they could do enough character dinners to fit everyone in lol play the cantina theme in the mexico tequila bar. Visitors would get dressed up like halloween.. peoples light sabers and blasters would be lighting up all over the park in the dark.. sell it as Star Wars invades Epcot! on select nights.. this fall or something.. $$
