Boy are you going to be surprised and have fun!!
Most quilters have never met a friend that they didn't know -- I mean they are mostly so friendly you feel like longtime friends real quick.
IF you happen to be near one who is 'superior' or judgmental or too quiet and unfriendly, please make a point to move!! Be more protective of your own feelings than theirs (worrying that moving will be rude to them) and just do it. You paid for the event, make the most of it!
Wish I were going to be there, too, I just love first timers!
