If I understand the rules correctly, Priceline guarantees double occupancy. That means the bed situation could be one king, or one queen, or one double, or two queens, or two doubles- whatever the hotel has available. IF you are going to take the chance on only one room in the 4* category in the Disney area, you might want to call the hotels that seem to be used most and ask what their bed accomodations are before you bid. Also ask if they have roll-aways/cots or cribs available, and if there's a charge. Otherwise I'd either bid for two rooms or look into a "regular" reservation.
