I’m not following why people think a minnie van is needed here? Unless a car seat is needed, a regular lyft or uber can also take you from WL to BC. BC will let rideshares in to drop people off, they just won’t let you park unless you’re a hotel guest.
If you don’t need the car seats (I do, so I use MV), the only place where MV’s really shine is the Magic Kingdom drop off, since they are the only rideshare that can actually drop you off at the park as opposed to the TTC.
