We have used the Magical Express for both of our trips to WDW in the past and loved it. However next Nov/Dec we are looking at doing a combo trip with some friends and hitting up USO first for a couple days and then finishing our trip at WDW. Can we still get out Magical Express tags but simply not use then on our arrival flight but then do use them when we are leaving WDW so we can use the bus and luggage drop off for our trip home? Does Disney care if you didn't use the arrival leg of the Magical Express but still want to use the Departure leg? Thanks!
