If I have 6 people in my party, and we all get FP+ for a given attraction at the same time, but only 4 of the people decide they actually want to go on the ride, can 2 of the people use the FP+ again for this ride (assuming there is still time left in the window after going the first time)? Would the 2 people going a second time need to physically have the MagicBands of the 2 people who didn't ride in order to get in the FP+ line a second time, or would the fact that the MDE accounts had been linked make this unnecessary?
