Katie and other first-time attendees,
Just a note about food. There are several food options in the Hollywood and Highland open-air mall where the multiplex with the smaller screens is located, including several fast-food options. These have been known to change from year to year, but several are located near the entrance to the multiplex, which is on the second level of the mall.
Across the side street from the Roosevelt is a Coffee Bean & Tea Leaf, and a fast-food Mexican place is only a few doors down. There's an In & Out Burger a block or so behind the Roosevelt (Californians swear by In & Out). There are restaurants and fast food close to the Egyptian Theater as well.
After the first day this will all make sense to you. The locations are within easy walking distance. On Hollywood Boulevard you'll have to push past tourists (not our film festival people) and people in tacky costumes trying to get cash from the tourists. This is the only down aspect of the festival, and it doesn't matter next to all the great things.
Do schedule time for meals. Some of us try to squeeze in one decent meal a day (granted, I once had dinner at 4:00 because of the movie schedule) along with breakfast at your hotel and a quick grab for another meal.
I've had a Classic Pass for the first six festivals, and that's always been a great choice for me. If there's a movie that's a must-see for you, show up an hour in advance to get your "Queue Card," which gives you a numbered place in line. They start seating about 20-30 minutes before the show starts. In six years I've never missed a movie this way, although at one of the smaller venues I cut it close and got one of the last six seats.
Do talk to people in line. All you have to do is ask, "What movies have you seen?"
