Yes, you will have to get in a ticket line to convert your VIP pass converted to a floor pass. Usually it is separated - diff booth than regular ticketing. Read the signs carefully.
Yes the lines form quickly and get long prior to opening for the Early Bird, so be prepared to stand in line for a while. You want front of line status you better be there early, I'd say 9ish. Seems like they are starting to get a line started even when they open the doors for us vendors at 8. Really good time to "map out" your strategy route while you stand there.
Like Ed said the first 30 - 40 minutes is hectic and a little bump and pushy coming in the door from what I can see from my table.
Just a note - Don't depend on the ATMs in the lobby to have cash after the first hour or so. They tap out quickly. Just keep your hand on your funds. Also don't expect every vendor to have card processor for their phone or a paypal account - cell phone reception varies with carrier and location within the event. Just be prepared.


ps - Dougie, I have a VIP reserved for you if you need it.
