We weren't all that close but our numbers were called out by the UC security and we were checked going through the door. It happened like this....My husband was 220 and I was 221. As the groups were being let in, one of the UC security yelled for #220 and my husband said that was him. The guard indicated that he was the cutoff, starting the next group of 25 or however many they were letting through at a time. He asked to see our numbers and then said that since we were only a group of two people, we'd be added to the end of the group ahead of us, not starting the next group, so we got shuffled forward towards the door. Then there was 3-4 security guys checking to see who was the end of the group (they knew that 221 - me - was the last one that should be let in) so we showed our numbers. That's when they realized 4 of the 5 guys directly ahead of us had no numbers. We told the guards that these guys (save for the one we didn't care about) had actually been sitting in line all day, we could vouch for that, but we didn't know them and weren't in their group. The guards started arguing with these guys about why they never got numbers (people had mentioned it to them, and they just mouthed off about how they didn't need to be bossed around, yadda yadda), and we showed our numbers again and were allowed to go around them to move forward to the bag check.
For day 2, we were in a party of four with numbers 212-215. I don't think we had to show our numbers going in, but the fan line people did come around and check everyone's name and number on the list before we went in. I think they only checked to 250 or so.
Maybe they were more jumpy last week because it was the first show?
