We have to seat you somewhere for the dinner.

This is a "first pass" attempt, taking into consideration specific requests from some people.
 
I will endevour to put you in groups of your choice, but,
this is a case of "first in, best dressed" and your specific request might not always be possible.

Anyway, the sit-down affair will only take about 1½ hours. Thereafter, you can move wherever you please!
