If you have not yet called Hugh's Room to book a ticket for this show (and you plan on going to it) I would recommend doing it soon.
No one else has posted about this yet, so I'm going to assume that no one has booked a "frucon table" yet. So if you tell them, when you book your ticket, that you are part of my group (my name is Kyla) then they will hopefully put us at the big table, or at least at tables close to each other.
The dinner reservation is for 7. If you don't want dinner (though the food there is really good!) you can still book your ticket, just tell them that you do not want dinner. Very simple.
