They are going to have to control that with the H-US debut…. Unless they want registered (paying ) guests to be disgruntled.
They already control entrance from SkyLiner to door access. Must have Magic Band from parking lot with luggage to open doors to closest elevators.
Also the level / door closest to the SkyLiner is not the same level as the lobby floor… therefore slightly confusing and they absolutely can not have unregistered guests wandering the hallways..
I expect security to be very strict . if anybody stayed at a monorail Resort last New Years Eve , you will understand Disney had protocol to tightly control access to MK and to firework viewing . I guess you consider a Covid NYE to be a good security dress rehearsal for the 50th .
Anyway hope the ToWL will soon Re-open.
