Bridal Table - Who Makes The Cut?

Hi all


We will be getting married in December, and in our bridal party are my sister and aunt (practically my big sister) as bridesmaids, and my future brother-in-Law as best man. Otherwise we will have 2 flower girls (3 years so they won’t be at the reception) and my 7 year old cousin (aunt’s son) as our page boy.
In our wedding reception we are having a rectangular table of 10 as the bridal table. This is where the problem begins - we will be having 2 sets of parents, my husband and I, but don’t know if what to do about the last 4 seats. Either we have my sister (15) and my cousin (page boy) along with my aunt and future brother in law (who will definitely be on the table), or we have my uncle and BIL’s wife, in place of my sister and cousin.
We may possibly be able to do a table of 12 but I am yet to confirm with the wedding venue so I am mulling over who to keep on the table??!
Option A; sister and cousin at the table, move my uncle and BIL’s wife together to a table of people they know/their age (BIL and his wife love interstate and don’t know anyone here but the wife is super social) OR
Option B; have my sister and cousin at another table and put my uncle and BIL’s wife on the table so they sit with their partners
Thoughts?
