Minnie vans or bus

We have reservations for hoop de du review on our arrival day @ 6:15pm. To save time we plan to use the Minnie van service so we don’t have to leave the resort as early as we would taking buses. We have a really early morning due to pre park opening breakfast the next day at Be our guest. With MK not opening until 9, would busses be running by 6:30? Is that early enough or should we take a Minnie van that morning too? Same thing with early morning hours at animal kingdom. Do the buses get you there early enough to rope drop efficiently?

All reports that I’ve heard say yes. Maybe not by 6:30am but probably by 7am or before.
