DH and I had early seating dinner so on the last morning breakfast is at 6 or 6:30 (I don't remember the exact time) and we were on the Mears van to WDW at 7:30. It is about an hour ride and then we went to check in at GF and it was off to MGM. We were probably there by 9:30 at the latest. If you are staying at a resort in the MK area you could hop on the monorail and be to the MK really fast after you check in at your resort. We had to wait for a bus at GF to get to MGM which took a little longer than the monorail does.
