We need check out of Port Orleans Riverside at 11:00 am, but our plane doesn't leave until almost 5:00. We were planning on doing a little shopping at DTD before we leave. Can we still use magic express, and if so, do they keep our luggage at the hotel until we actually leave for the airport? I'd hate to have to drag my luggage all over Downtown Disney. And do we have to go back to our resort to catch magic express or can we catch it from Downtown Disney?
