We are meeting my inlaws and our neice at WDW. We are staying at separate resorts, and they are arriving about 4 days after us. We want to have a few meals together. When our reservation opens at 180 days out, can we make reservations for seven, rather than for just the four of us? I ask because technically, their date for making dinner reservations wouldn't start until 4 days later, but I would want the best chance of getting reservations for 7.
