The transfers go only to resorts, not the parks. So are you asking how long it would take you until you are at the park? Which resort would you be going to? It really can vary based on how full the bus is when you get on (you have to wait until it fills so that could be 5-20 minutes) and its about an hour drive and then it varies based on how many resorts you have to stop at before you get to yours. (Could add another 30-45 minutes to the process). Then once at the resort, transportation to the MK depends on which resort you are at.
