Thanks a lot!I went last year on Dec 6th thinking it would be wildly busy with the big anniversary the next day - it was not. However, the USS Arizona wasn't open yet from refurb. Maybe this year will be busier? Are you planning on trying to get a ticket 24 hours before, showing up at 7am for the line, or showing up later in the day? If you can get a guaranteed ticket, then I wouldn't worry about the level of crowds as it is a very wide open area that can handle large crowds.
