Basically you get reserved seats to the Fantasmic show with your dinner reservation. There's no extra cost for dinner . . . just a limited number of the packages available. So book it as early as you can. Our family loves it. We eat anyway and it saves you the waiting to get in for the "standby" seating at the show. It doesn't give center stage seats but the show is great from every angle. But if you or someone in your party wants to sit centerstage, you'd be better off waiting in the line to sit. The reserved seating is on the side of the theater closest to the theater exit. Have fun!
