The timing and location of landfall for the hurricane is not set in stone, but making reservation changes need to be done sooner than later. We went through Matthew and Michael (a couple of other minor hurricanes and a few tropical storms) at Disney. Michael took a last minute turn and all we had was rain. Michael, on the other hand, made his presence felt for about 36 hours. At this point, Disney has instituted no shutdowns, but rest assured the Mouse is watching and will put a plan into action as soon as they are confident of the track/timing/magnitude of this storm.
Having been through a few hurricanes at Disney--I would be sure I was checked into whatever resort I chose by Monday (provided this storm stays on track AND timing is for overnight Monday into Tuesday) and stay put--that would leave out your night at AoA.
First of all, depending on when/if the storm hits, there could be road closures lock downs or any number of things that would prevent a move on Tuesday. Unfortunately, with hurricanes, tropical storms and the like--there is no way of knowing how they will behave until nearer in time. I would make a plan to stay put where you are now (provided you could extend) or make that move on Monday to AKL. But that's just me.
