A day of popcorn

From lordoftherings.net:
From December 5 - 11, the studio will release 100-150 35mm prints of the Special Extended Edition of The Fellowship of the Ring in cities across the country. On December 12 - 15, these prints will be replaced with Special Extended Edition prints of The Two Towers. On Monday, December 8, and Monday, December 15, both films will be presented back-to-back. Then, on Tuesday, December 16, participating theaters will show a one-time-only marathon of both Extended Edition prints followed by an 11pm screening of The Lord of the Rings: The Return of the King. The official opening of the film will commence at 12:01 AM on Wednesday, December 17, 2003.
Okay, is there any doubt where I plan to be for about 12 hours from Tuesday December 16 to about 2 in the morning on December 17? Will there be chamberpots under each seat, or will I have to bring my own?
