On our last day, we will be in the parks until mid-afternoon and then fly out around dinner time. I hear we can now check our luggage for the flight right at the hotel. What happens if we mess up and don't get back to the hotel for our designated DME bus? Can we just hop on the next one? Is there a schedule of how often they arrive, or is it a fairly steady stream like there is at the airport when you arrive?

Also, will our pre-checked luggage go on to the airport without us, or will we need to confirm it's location when we get on the DME bus?

Of course we plan to allow plenty of time, but just in cases buses are late, or lines are longer than quoted, etc. . . . Thanks.
