You could save time
It's hard to say how much since you never know what the wait on a bus will be.
You need to be at the AK WL bus stop at least an hour before your ADR. I believe WL bus stops at other resorts too, but can't really remember exact order or which ones.
A ride share (or Minnie Van) will be more of a known because you will only have to wait the few minutes for the ride to come. Then the travel time. Travel time is the same of course. It's the unknown wait that makes it hard.
Personally, I dislike using Minnie Vans to/from AK. They have the worse drop off/pick up spot, at the very last/furthest bus stop. Regular ride share is right up front. I use it for almost every trip to AK
