We traveled Easter week with a party of 10. For every ADR I made, I was told we would be separated at two, sometimes even three tables. However, they seated us all together at every restaurant. At Prime Time, they even told us when we checked in at the podium that we would be separated, and yet they managed to seat us all at one table (two pushed together, actually). That doesn't mean that will happen every time, of course, but there is a good possibility that you will be seated together for at least some of your meals. Good luck!
