I have not been during Christmastime, but have during the busy summer and Columbus Day weekend. In the summer on an 8 day we lined up 1 hour and 15 min before showtime, but we wanted front row. That was with dining package. Columbus Day weekend, equally as busy, we got in line about 1 hr and 5 min before showtime. Once we got our spots on the bridge (blue FP), we take turns leaving (1 person needs to stay with your stuff or you will lose your spot). Take a blanket or a jacket to lie on the ground to save spots. Everyone should return by 30 min before, because they make people stand up, move forward, that kind of thing. Harder to keep spot. We take a bathroom break, get a Mickey Bar, and wait for the show. During Christmas week I would check about 90 minutes before showtime and see if people are lining up. The CM’s will have signs for each section so you will know where to go. We find that when they open up the blue FP area, most people head for the main viewing area and don’t seem to notice or care about the bridge location. That will work to your advantage! Go 2/3 of the way up, and your view should be great. Trying this again in 26 days, will let you know if anything has changed since last visit.
