Let me be clear. My son is the youngest cousin. My husband's cousins' children are teens/adults. Everyone is scattered throughout the country so if they do come, he will not know anyone. He will be stuck with way younger kids in a very weird situation. Yes, he ultimately will be fine, but upset that he can't go sit with his cousins. There was a handwritten note from the bride in the invitation asking us to drop him off in the kids room.
We still haven't decided what to do.
OP, you are approaching this in a really strange way. He can hang out with is cousins at the 3+ hour reception, where he can actually talk with them. Not being able to sit quietly with them at a religious ceremony is not a big deal at all.
Also, this may be time for some self-reflection. There is a reason the bride and groom requested this. Is your son sometimes disruptive? There's a big difference between an immature 9 yo and a mature 13 yo. If you take an honest look at this, you may begin to understand.
