Another Dining Reservation question

[Pegct]

Will be sailing the Mediterranean Odessy at the end of September. There are six couples sailing together who booked 2 different cabin(DV 6 and V 2) categories. I have a few questions regarding dinner reservations.

 

1) When you make dining room reservations prior to embarkation can you only reserve for 2 people in your cabin or make it for 4 to include passengers  booked in a lower category.  Will be sailing in DV 6 category but my sailing buddies in V1 or V2 and we would like to eat together especially the specialty restaurants. 

2) Does Viking Ocean cruises have large tables that can seat 12 individuals in main restaurants or should we just reserve two tables close by that can accommodate 6? 
 

Thank you!
