Thanks Mattp and alc for the replies! This info will help a bunch! And don't worry alc, I am sure there are enough seats for us to go around!
For the record, I think it's fun to plan this stuff, which is why I am doing my research well in advance (although, not as far in advance as you, alc!) and I would never pay someone $100 to do this for me! Let the good times roll!
