I live in Portland, OR where many of the scenes were filmed. There is one place, where the "prom" scene was filmed that is offering a "prom party" for Twilight fans which includes:
November 20th, 21st Come Dance Where they Danced
Come to the Prom at The View Point Inn. Actual scenes from the movie will be recreated using the real sets from filming. Sets, props, photos and memorabilia will be up for viewing. Come enjoy a Monte Carlo night like Bella and Edward. Admission is $47. Price includes admission to the Prom, a movie ticket for the midnight showing of the film at the Sandy Cinema, food and a non-alcoholic beverage, a Twilight t-shirt, a Twilight poster and a copy of a never before seen photo from filming.
