Give me a sign....
First-time con-goer suggests: more signs to the registration area.
I went to the Pre-Con Mixer at The Zoo and noticed, "Whoa! People with badges and bags! Is registration already open?" (I'd thought I'd have to wait until Friday.) Many helpful folks helped me find my way to the registration room...
Any chance that we could have more signs next year showing the way between venues at the Westin and in the Convention Center? It would definitely be very helpful for us first-timers who have a tendency to get lost in indoor spaces...

Definitely taken under advisement.
