We are heading to Florida next month to visit family and do WDW. We will be staying at POFQ. My brother and his wife will be driving us to the resort. My other brother, his wife and my father will be joining us. Just me and my husband are staying but we thought it would be nice for all of us to have dinner together. I've made reservations at the Boatswright Restaurant for the seven of us. Question: can me and my husband use our DDP for our part of the dinner and if my father is not up to the trip, can we just have 6 in our party or do I need to change in advance?
