It's sort of iffy, I think. IF I recall correctly, you're not supposed to bring wooden weapons (ie bokken, shinai, etc.) to the convention, but some staff are more lenient and let it go anyway. To completely abide by the rules without complication is to either bring a light/harmless substitute like foam, plastic, etc, or not at all. I hard a hard time inquiring about weaponry, myself, and it proves to be quite troublesome. And even if you can bring them, some things are peacebonded to the point that they're pointless to bring altogether-- like prop guns sometimes are peacebonded to their holsters so you can't take them out to pose with. Sometimes, the silliest things get peacebonded, too... like people's signs, plushies, what have you.
I understand signs, since peacebonding is more of a way to make sure you understand the rules, and signs are frowned upon, but... plushies? How big/heavy were the plushies? Were people using them to attack others?
Last year I had my cheap plastic lightsabers peacebonded so many times. The first thing I did after waking up was go get them peacebonded because I wanted to be a good con-goer. But then the plastic ties fell off and I lost them. One of the bands was giving autographs, so my plan was to go buy their CD and get their autograph for my friend, and then head back to get them peacebonded. Well, on my way I was asked by three different people to get my lightsabers peacebonded. On my way out of the autograph room though (I don't remember where it was.. dealer's hall maybe?) One guy actually stopped me and peacebonded them for me because he had the stuff with him. Of course, I only needed the lightsabers peacebonded to show that I understand the rules, because they're the kind where if I hit someone with them they'll either break, bend, or retract. But I learned of something really cool that day... wandering emergency peacebonders.
