DCL transport will only take you to the resort where you have a hotel reservation. You can't just get dropped off at a different resort. It can take time for the resort buses to leave. We waiting on our GF bus for 45 minutes and we didn't arrive at GF until after 10:30.
If you have someplace you need to be before noon on embarkation day I recommend arranging your own transport such as ride share or car service.
