Depending on when Early Park Entry starts, you might be able to get away with Disney Transportation, but I second the Minnie Van suggestion. It's bookable through the Lyft app, and though it is a bit more expensive than a standard Lyft (you're probably looking at $35-$40 for FQ-MK), I think it's totally worth it as they have the ability to drive you directly where you need to go. In this instance, Minnie Vans will be able to drop off directly at the MK bus station, where a standard Lyft/Uber would have to drop you off at the TTC.
