Carnival really has no control over what aTravel Agent does or does not do. They are independant of Carnvial.
I dont know if this would work or not, but I would try contacting Carnival Group Travel. Perhaps they will be able to do something for you.
The only other option: As soon as you board ship, go to the dining room and ask to speak to the Maitre D'. He may be able to rearrange the dinner seating for everyone. But 24 people is really a lot to change the seating for.
Now, if you had booked directly through Carnival, with their Personal Vacation Planner, It would be no problem. My sister's extended family of 16 went on a cruise. And their PVP had them at tables right next to each other with the same waiters crew serving everyone.
Best of luck, and keep us informed how you make out.
